• Hi khashabolla,

  Thank you for posting in MSDN forum.

  .NET Framework 3.5 is included in Win 10, so you couldn’t install it from outside, no matter web installer or standalone installer.

  So, you may first check if the .NET Framework 3.5 is available in the Control Panel on Windows 10 Technical Preview and if available, you may enable it from the Control Panel to install it on the computer. To check if the.NET Framework 3.5 is available in Control
  Panel and to enable it, please follow these steps:

  a) Press “Windows Logo” + “R” keys on the keyboard.

  b) Type “appwiz.cpl” in the “Run” command box and press “ENTER”.

  c) In the “Programs and Features” window, click on the link “Turn Windows features on or off”.

  d) Check if the “.NET Framework 3.5 (includes .NET 2.0 and 3.0)” option is available in it.

  e) If yes, then enable it and then click on “OK”.

  f) Follow the on-screen instructions to complete the installation and restart the computer, if prompted.

  This will install the .NET Framework 3.5 feature on the computer. There is also another way by which .NET Framework 3.5 gets installed on the computer. This is done by the apps on demand.
  

  If an app requires the .NET Framework 3.5, but doesn’t find that version enabled on your computer, it displays the prompt for installing the .NET Framework 3.5 on demand, either during installation, or when you run the app for the first time after
  its installation. In this prompt, you can choose the option “Install this feature” to enable the .NET Framework 3.5 on the computer.

  Best Regards,

• I had this problem as well on my machine at work. Try doing the following it worked and allowed me to download the .Net Framework 3.5 on my Windows 10 PC :  Go into RegEdit and set the HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU
  folder.  DoubleClick on UseWUServer(UseWindowsUpdateServer) and change the value to 0.  If the value is already 0 this fix may not work for you.  You may need to restart afterwards.

  If this works for you please mark as answer.

• This worked perfectly for me!! Thank YOU!!

• Thanks this works for me!!! I had been looking for a resolution over 2 hrs.

• This does not work!  I follow theses instructions, pretending I have not tried it a hundred times myself, and the outcome is no different than before.  This is a BIG problem.  I am rolling Windows 10 out to more than a 200 machines and I
  cannot have these problems. I have tried enabling the .NET 3.5 immediately after installing the image, prior to any other installations, updates, or profile moves; the problem comes up later.  I started removing installed Security updates to see if that
  would help, it doesn’t.  Please help, this is a BIG problem for me and many others. 

• Unfortunately, this does not work for me.  I get the same error message.  I downloaded the 3.5 installer and that would not even complete the install for me.  This is not just one machine, this is many. Please, any other ideas you have would
  be much appreciated. 

• This registry change worked for me. Thanks.

• It helped. Thanks a lot for the answer

• Not sure how this got marked as the correct answer given that the orginal query actually states the the user already tried this approach

  When I try to enable the .NET Framework from windows features I got this message
  Windows couldn’t find required files to complete the requested changes. Make sure you’re connected to the internet and try again.

• This registry edit seemed to help with installing this and some other problems with finding updates, such as with SQL Server Express.  Thanks.

• This worked for me, but to reiterate, a restart was indeed required.

• Yes! Thanks so much, this worked after trying multiple other solutions. Note also that you have to run regedit as administrator or you won’t be able to change the value to 0.

• The registry edit worked for me, thanks!  It did not work until I restarted the computer though.  After restarting, it worked fine! 

• DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

• Registry edit worked for me. Thx!  You could also tell the person or dept. who manages the internal WSUS machine to approve the dot Net 3.5 installer package.  That would most likely work as well once the source files are downloaded to WSUS.

• This worked great for me.  Thanks.

• Regedit and reboot. Spot on thanks.

• This one worked for me . Thankyoi

• Worked for me here!!!

  Windows 10 Pro, fresh lappy install…

  Thanks you!!!

• Removing the workstation from the domain also makes allows the feature to install. It seems that a group policy is configuring a WSUS server that is either down or not working. Fixing the WSUS config would also like fix the problem. 

• Thx for this, fixed it for me too!

• Many thanks for this fix, I had been looking for some time. Regards,

• This worked for me. Thanks.

• Windows10 online update create this folder:
  C:ESDWindowssourcessxs
  There are just one file. (microsoft-windows-netfx3-ondemand-package)

  Take windows 8.1 installation media and copy files from x:sourcessxs to C:ESDWindowssourcessxs  (1174 files)
  run cmd.exe as administrator

  execute this command
  Dism /online /enable-feature /featurename:NetFx3 /All /LimitAccess /Source:C:ESDWindowssourcessxs

  The dism command has worked for me on several machines.  However, what I did was copy the Windows 10 .iso file to the hdd and them mount it.  Then, I use the drive letter of the mounted .iso instead of C:ESD in the dism command.

• THIS is the fix that worked! Thanks, Paul Bill!

• Thank you Paul! This just helped me. 

• Did you follow through on this, ie contacting WSUS admin and asking them to approve the 3.5 updates? I will trying this and post back if it works as the workaround is a poor solution in my opinion. If the machine is making use of WSUS no one should be circumventing
  that unless all else fails and your post was the first one I saw that had this idea which I believe should be the recommended and approved solution (if it works that is).

• is not working.i don’t see where the install this feature is

• Perfect, it works like a charm. Just remember to run Regedit as an administrator and do a restart when done.

• This worked perfectly for me also after a couple of hours of internet search. Thanks for posting this , as already mentioned ,Just remember to restart the PC..

• Office Windows 10, version 1703 (OS Build 15063.674)

  I have tried to install by using either dotnetfx35Setup.exe or dotnetfx35.exe(full package) without success. 

  Thanks for your registry solution which did resolve this issue. The office PC was <g class=»gr_ gr_419 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del» data-gr-id=»419″ id=»419″>setup</g>
  to receive the update from WSUS server which I assume the value «1» to force PC only get <g class=»gr_ gr_578 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep» data-gr-id=»578″
  id=»578″>update</g> from internal WSUS. 

  After change value to «0», it works.

• Thank you very much, Harvey,

  That was the winning hint after testing douzend of other hints. The only I did change was I did use the Windows 10 installation media.

  Another example of someone under the Microsoft moniker who should not be allowed to mark posts as answers…

  This is not the fix to the poster’s issue.

  The regedit answer is the solution (albeit a bit of a kluge).  That should be marked as the answer.

• doesn’t work for me

  there’s nothing like that in my Win 10 registry

• Dear Microsoft.

  Have you lost your mind? This issue is 1 year old and it still reproducible. Installing one of your products to another your product requires 1 hour research and hacking registry. 

  This is really charming, one «Moderator» (Jiayi Li) wrote senseless and helpless post and another Moderator (Wen Xu) marked it as answer. I hope that you will get bonus for your great hard work

  And finally, thanks Paul Bill for answer that helped me. Paul’s post has 45 votes, but it isn’t marked as an answer… Probably because he is not a moderator.

• Which registry change? I searched and searched, found nothing except repetitions that «it works». The DSIM command does not work either, it complains with error 50.

• Hi,

  In Windows 10  the issue is reolved if you run windows update and let it complete and restart when required. After restart the required update for installing .netfx3 is able to complete itself. (internet required)

  Tried all below solutions but failed. There is possibility that when windows update restart is pending then it won’t get any more updates till it is completed and restarted.

• Hello,

  I am hoping you can please help me as I have been trying to install net 3.5 for many days and many many hour spent. This is the first instance I have seen this fix yet the directory does not exist for me. in regedit as admin I can only find HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows
  and WindowsUpdate is not there. I also can find nothing with AU. Also the error I have when trying to install 3.5 from my mounted drive is this:

  Error: 50

  The operation is complete but NetFx3 feature was not enabled.

  The DISM log file can be found at C:WindowsLogsDISMdism.log

  After this checking my log file I will see this error :

  2018-01-11 10:45:38, Error                 DISM   DISM Package Manager: PID=3820 TID=3964 Parent features must be enabled before this feature can be enabled. «NetFx3»

  So something about Parent features must be enabled. Any help would really be appreciated, thank you

• same as you. i tried two given solutions like you, and now, every time I’m booting up my laptop, windows requires me restart my laptop to complete installing .NET FRAMEWORK 3.5.

  Damn it!

  I have just the same problem.

• Nope , not a solution for me. Tried all methods suggested after a day on forums. Inlcuding reg mods still no joy I get the same as other users when using dsim command which is error 50 Basically it appears to have installed 3.5 fine as it is readily available
  for selection under windows features. However if i select it , install process seems to go fine and asks for restart. doesnt matter how many times i try this and restart it is still not enabled under windows features. Please someone help with this . (recently
  fresh installed windows 10pro 64 anniversary pack which started this problem. previous install of windows 10 pro 64 wasnt anniversary and 3.5 worked fine from the start) something to do with the 4.6 in anniversary taking over and disabling 3.5 for good ???????????????

• This should not be marked as the answer to the issue the OP had.

  More worrisome is that this is still an issue on a fresh fully updated Windows 10 install. If this is working as designed, which it may be, we could at least be provided with a meaningful error message.

• Winner winner chicken dinner!

• Say,  I was int he same boat where none of the above suggestions worked. However, I ran across a fix in another post that worked for me.  Essentially, reboot into safe mode (repair mode, I guess) and install it from there.

  -Restart from power button in windows with ‘shift’ key held down. 

  -Go to troubleshoot, then advanced options

  -startup repair

  -log in to windows

  -go to Control panel->programs and features->Turn Windows features on (with your sexy moves) and off

  -Check the box by the install .net framework 3.5 

  -watch it finally work (hopefully!)

  restart and it should finally stay checked on.

• After trying many different solutions, this was the one that did the trick. Thank you!

• This worked for me as well. Thank you!

• After many attempts and hours of researching — what worked for me to fix the problem.

  Problem: Trying to Add Windows Feature — .NET Framework 3.5 (includes .NET 2.0 and 3.0). After attempting to use the Dism command line within normal Windows use — kept getting the «Error 50» message and failure to install the above. My system is
  Windows 10 Pro 64-bit; the original Windows 10 install disk inserted into my DVD drive («E»).

  Solution: Reboot system — holding down the «shift» key right after or when you see your Bios screen — you need to be able to have the option — «To specify an advanced option for this choice, press F8.» [note — your screen should also
  be highlighting that you are choosing Windows 10 to start your system]

  Next step: choose to start your system with «Safe Mode with Command Prompt». Note — even on a fast system you need to wait a minute or 2 until the c:windows system32> prompt appears [I have an AMD Ryzen 1700x with a Samsung 960EVO SSD drive
  plus 32GB high speed RAM and it takes a minute or so to load]

  Next step: [you need to have a DOS window with c:windowssystem32> showing or the next command won’t work.

  Type in the Dism command (my DVD drive is «E»

  dism /online /enable-feature /featurename:NetFx3 /All /Source:e:sourcessxs /LimitAccess

  Your system should reply with «Deployment Image Servicing and Management tool  — Version: 10.0.16299.15

  My system stated also — Image Version: 10.0.16299.214

  Then processed 100.0% — enabling feature(s) and stated «The operation completed successfully.»

  Final step: Reboot and verify the installation of «.NET Framework 3.5» by checking in through the Control Panel of Windows.

  Hope this help others.

  Really Micro$oft — what a royal pain in the A… We really don’t need this kind of stuff happening. You guys need to check your work a lot better. This Creators update has been a nightmare!

  calling the command line  from «Safe Mode with Command Prompt»

  dism /online /enable-feature /featurename:NetFx3 /All /Source:e:sourcessxs /LimitAccess

  To make it easier  I copied the cab-file from sourcessxs   to C:  and saved the command line

  dism /online /enable-feature /featurename:NetFx3 /All /Source:C: /LimitAccess

  to a batch-file  net35.bat  also at C:

• i cant find the windows update folder are you sure its the right directory !?

• 2 hours ? i looking for almost a year and a half man youre lucky mate

• In order to resolve this issue, you need the installation media.

  Must be an Administrator to do this

  Insert the Installation Media

  Copy the file from <CDROM>SourcesSXS to C:Temp

  Launch an elevated command prompt

  execute this command
  Dism /online /enable-feature /featurename:NetFx3 /All /LimitAccess /Source:C:Tempsourcessxs

• I had the same problem, the HKEY/LOCALMACHINE…/AU folder does not exist in the RegEdit folder on my computer. What worked for me:

  1. Enable the WindowsUpdate service via ‘computer management’ —> ‘services and applications’ —> double click ‘services’ and search for ‘windows update’ service —> enable

  2. Once the windows update service is enabled go to ‘control panel’ —> ‘program and features’ —>’turn windows features on or off’ —> check the ‘.net framework 3.5’ box and click OK

  3. Windows will now download the necessary files (takes about 5 to 10min)

  Hope this helps!

• This worked for me.

  Make sure Computer is connected to Internet.

  Go to services.msc

  Scroll down to Windows Update

  Right Click, then Properties

  Make sure Start Type is Automatic, then Start the service by clicking on Start Button in same dialog box

  Now Go to Control Panel > Programs > Programs and Features > Turn Windows features on or off

  In Windows Features Check all boxes for .NET Framework 3.5 (includes .NET 2.0 and 3.0), then OK

  Windows should try to connect on internet and install this .NET Framework 3.5

• Windows10 online update create this folder:
  C:ESDWindowssourcessxs
  There are just one file. (microsoft-windows-netfx3-ondemand-package)

  Take windows 8.1 installation media and copy files from x:sourcessxs to C:ESDWindowssourcessxs  (1174 files)
  run cmd.exe as administrator

  execute this command
  Dism /online /enable-feature /featurename:NetFx3 /All /LimitAccess /Source:C:ESDWindowssourcessxs

  This solution worked for me. OS Build: 14393.1944

  I copied the microsoft-windows-netfx3-ondemand-package.cab from my Windows 10 installer.

• Say,  I was int he same boat where none of the above suggestions worked. However, I ran across a fix in another post that worked for me.  Essentially, reboot into safe mode (repair mode, I guess) and install it from there.

  -Restart from power button in windows with ‘shift’ key held down. 

  -Go to troubleshoot, then advanced options

  -startup repair

  -log in to windows

  -go to Control panel->programs and features->Turn Windows features on (with your sexy moves) and off

  -Check the box by the install .net framework 3.5 

  -watch it finally work (hopefully!)

  restart and it should finally stay checked on.

  WOW! I never knew Startup Repair actually did anything besides annoying people!
  This worked like a charm, instead of going direcctly to pop-up asking to reboot, it actually did something for a few seconds, then it said it was activated, not even needed to reboot.

  Thank you very much, whoever you are.

• I tried this and No luck! Although my registry value was set to 1 and I changed it to 0.

  ComputerHKEY_MachineSoftwarePoliciesMicrosoftWindowsWindowsUpdateAU  change the value of USeWUServer to 0

  Windows 10 Pro.

• You are the man! worked great been trying to fix for some time.

• Thank you , it’s works for me .

  Good day !

• Worked perfectly … thank you!

• I had this problem as well on my machine at work. Try doing the following it worked and allowed me to download the .Net Framework 3.5 on my Windows 10 PC :  Go into RegEdit and set the HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU
  folder.  DoubleClick on UseWUServer(UseWindowsUpdateServer) and change the value to 0.  If the value is already 0 this fix may not work for you.  You may need to restart afterwards.

  If this works for you please mark as answer.

  Thanks a ton, most helpful answer on this by far.

  The registry worked for me. I had an issue with a laptop at work! Thank you!

  If this works for you please mark as answer.

  Can this please be marked as the real answer?
  The marked answer will give the same error as trying to install from Win Update. This Reg fix allows the download through Windows Features to complete.

• i dont have the registry value «WindowsUpdateAU» under HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows.

  i have also tried every other suggestion in this blog but nothing works for me.

  i also get the error i found every time is «the system cannot find the file specified error code 0x80070002»

  any ideas please?

• This did not work for me. I get the error code: 0x800F0954.

  I also have tried everything listed in the initial question. This is a fresh install of Windows 10.

• This worked. I had to run the DISM.exe from the command line to install .NET 3.5

• Worked for me after doing all the same steps as the original poster. Thank you!

• https://www.microsoft.com/en-gb/download/details.aspx?id=25150

• The Full Package installer should work:

  https://www.microsoft.com/en-gb/download/details.aspx?id=25150

• None of the above didn’t worked for me, but this did: 

  Downlad Windows 10 upgrade
  https://download.microsoft.com/download/E/0/A/E0A1E6A8-26F8-4399-9C22-27419BC37B51/Windows10Upgrade9252.exe

  Wait like forever

  Try once again to enable dotNet Framework 3.5 in System Function whatever

  Should work. 

• This finally worked for me!  All of the other options failed.  The registry key was not on my system.  Rebooting to safe mode with command line is the ONLY thing that worked.  I spent hours on this… thank you!

• I tried to do this RegEdit fix but I don’t have a WindowsUpdate or AU folder. Why would I be missing those?

• This may or may not fix the error for others, but it worked on mine.

  From the following 2 webpages I was able to clarify the Microsoft instructions on the first webpage for fixing the 0x800F081F error. It would be nice if Microsoft would clarify the first webpage since it is linked in the 0x800F081F Error window in Windows
  10.

  https://support.microsoft.com/en-us/help/2734782/net-framework-3-5-installation-error-0x800f0906-0x800f081f-0x800f0907

  https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-8.1-and-8/hh825020(v=win.10)

  Resolution for Windows 10
  Error code 0x800F0906, 0x800F081F, or 0x800F0907

  To fix the error codes for Windows 10, follow these steps:

  1. Download the Windows Media Creation tool, and create an ISO image locally, or create an image for the version of Windows that you have installed.

  2. Open the group policy editor. For example, on a computer that is running Windows 10, from the start screen, type Edit Group Policy, and then select Edit Group Policy to open the Group Policy Editor.

  3. Click Computer Configuration, click Administrative Templates, click
  System, and then double-click the Specify settings for optional component installation and component repair setting.

  Also follow these steps:

  1. Mount the ISO image that’s created in step 1 above.

  2. In the window opened in step 3 above, select Enabled, and point the «Alternate source file path» to the ISO X:sourcessxs folder from the mounted ISO.   <— «X:» is your
  mounted drive letter for the ISO

  3. Run the gpupdate /force from the command line.    <— I ran this step as Admin (Admin may not be needed)

  4. Now add the .Net framework feature.

  I didn’t need to restart.  Hope this works for people who couldn’t get the methods above to work.

  on an admin command prompt worked for me. Thanks Alex.

• I actually signed in to say thank you as this was driving me up the wall and your solution was what fixed my issue

• This worked for me. Thank you very much

  Worked 100% for me thanks Paul

• This works for me. I have a WIndows 10 Enterprise running as VMware workstation host and couple WIndows 10 Enterprise image running as VMware VM. So far, this only happened with my WIn10 host machine. ALl Win10 VMs don’t have this issue. Strange!

• Windows 10, 10.0.17134 Build 17134, the path was ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftPolicyManagerdefaultUpdateAllowUpdateService

  Change «Value» to 0

• Tried all the options from this post, this was the one that worked for me. Had to delete the last two folders of the path.

  I inserted the Windows 10 Pro Disc and copied the only file inside this directory:

  <CDROM>SourcesSXS

  into this directory:

  C:Temp

  Then launched command prompt as admin and pasted this:

  Dism /online /enable-feature /featurename:NetFx3 /All /LimitAccess /Source:C:Temp

  There was a percentage of the progress, then finally ended up at 100% and saying that it completed successfully.

  Thanks all for the help.

• In my case, it was a corrupted installation of «Microsoft Visual C++ 2017 Redistributable (x64)».

  I went to Control Panel -> Programs and Features -> Uninstall or change a program -> Right clicked «Microsoft Visual C++ 2017 Redistributable (x64)» and uninstall.

  When the window appears click repair and wait for the operation to complete then reboot. After that everything worked fine

• Worked for me thanks. You should get an interview for Microsoft

• Superb! FYI: repair stated that it could not repair the system, however, after returning to program and features, it actually worked. Thanks!!!

• I tried this for installation of .Net framework 3.5  but getting following error:

  The changes couldn’t be completed. Please reboot your system and try again. Error code 0x800F0950

• This worked perfect!!  Thank You!!

  Should I change the value back to 1 ??

  Thanks Again!!!

• This worked form me also!  Thank you!

• Brilliant. just exporting the file in the location that that file is copied (you don’t have to extract all of it)

• GOD BLESS YOU! IT WORKED! I was in dispire after trying all Microsoft recommended things. Yours HELPED! THANK YOU!!!

• In Given Directory after RegEdit there is no windows Update option in windows Directory . 
  Suggest me some thing so that it work 

• Thank you. This solved the problem

• It is a loop of the problem.

• Changing the registry entry to 0 worked for me.  Our environment uses WSUS and the failure was telling me that it could not find the files using WSUS. After changing the registry, I rebooted and retried checking the box to allow MS to download the
  files. it was able to go out and get the .net files.

  This fixed it for me. I can’t believe I had to do this on my brand new Surface Pro. This was an issue almost TWO  YEARS AGO, and I still had to find this registry hack on a forum to fix it? Get it together MS. Seriously. 

• its worked perfectly for me!!  thank you.

• Thank you.  Removing from the domain, restarting, deleted the registry entry.  I was then able to go to the control panel and turn Windows features on/off for .NET 2.0 and 3.5.

• Great. It’s working fine. Thanks for your support and sharing knowledge.

• Thank you very Much. This helped me after I’ve struggled for days.

• It worked! Thanks for your contribution to the community.

• This saved me a ton of time and frustration.  Thanks!

• This worked.  Reboot was needed.  Thank you!!! 

• MVP — Hello from 2019 — Thanks for the save. 

• Ironically, 2019 here, he didn’t specify where this actually works, and if you still a full installer (like I did at first) it doesn’t actually work — instead you need to install it through the control panel -> windows and features. 

  Not exactly sure why that worked, but when none of the installers work, I tried that, and well, it worked. 

• This worked for me. Thanks

• Bravo!  So SIMPLE it was painful, but thank you so much!…

• This worked for me!

  Thanks!

• Thank you!

  Worked for me.

• Thank you Paul!  Life saver on this fix…

• Close! and thank you for the clue

  Set the reg key above and restart Windows update Service

• Thanks this worked for me too with the Microsoft Windows Server 2019 Standard. it was nightmare as I wasted time one after the other and finally hit the jackpot. Thanks @jkbarr30

  Error code 0x800F0906, 0x800F081F, or 0x800F0907

  4. Now add the .Net framework feature.

  I didn’t need to restart.  Hope this works for people who couldn’t get the methods above to work.

  This worked for me. Windows 10 Pro, old install. I just needed to reinstall .NET 3.5 for a reason.

• Yes this Work — Must restart then install feature

• Thanks Paul for this fix. It has certainly worked for many but I wanted to add one thing here. This fix may not work for corporate environment with WSUS and GPOs in place. 

  Fix for this is to download the latest ISO of Windows 10 and point the installer to it 

  CMD -> dism /online /enable-feature /featurename:NetFX3 /all /Source:’newSXSfolderfromISO’ /LimitAccess

  in my case command looks like -> dism /online /enable-feature /featurename:NetFX3 /all /Source:E:supportsxs /LimitAccess

  worked very well. thanks a lot

• Hi Guys 

  This worked perfectly as soon as I changed the value to 1=0 

  I was able to enable the Feature for .Net 

  Thanks a million

• I can find my way here HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows  But there is no WindowsUpdateAU Folder listed 

• What worked for me was going into gpedit.msc, administrative templates, windows components, windows updates. There were a few items in there that were enabled such as ‘specify intranet windows update location’. I disabled those and then it worked. You
  need admin rights to do that. 

• Installing .NET Framework 3.5 is not always the same solution depending of the Windows version !

  This is my solution to install this package «Offline» without Internet access:

  Windows 7/Windows Server 2008 R2:

  DISM.EXE /Online /Enable-Feature /FeatureName:NetFx3 /NoRestart

  Windows 8.1/Windows Server 2012 R2:

  Put original DVD / ISO in the computer (D:)

  DISM.EXE /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:sourcessxs

  Windows 10 (1507 — LTSB 2015 Or 1607 — LTSB 2016):

  CAB File is available on the DVD /ISO, assume is D:

  DISM.EXE /Online /Add-Package /PackagePath:»D:sourcessxsMicrosoft-Windows-NetFx3-OnDemand-Package.cab»

  Windows 10 (1809 — LTSC 2019):

  CAB File is available on the DVD / ISO, assume is D:

  DISM.EXE /Online /Add-Package /PackagePath:»D:sourcessxsmicrosoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab» /NoRestart 

  Then install language pack also on the DVD / ISO (Sample for French Canada):

  DISM.EXE /Online /Add-Package /PackagePath:»Microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~fr-CA~.cab» /NoRestart

• This is exactly a description of the process which the OP describes as failing with the error code 0x800F081F. With respect, what we are looking for is a solution to the problem, not a description of what doesn’t work.

• Try Go into RegEdit and set the HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU folder.  DoubleClick on UseWUServer(UseWindowsUpdateServer)
  and change the value to 0.  

  and Restart your machine. That should do the trick!

• this help. perfect! yey…

  18343 19h1 insider preview (slow)… Can you tell me how can I do this….

• This worked for me, thank you!

• Thank you that worked. Question — do you need to switch it back after the install is complete?

• This registry change works.  This should be the accepted answer, not the fluff response from the mod.

• Thank you, this worked for me.

• This worked for me! Thank you! Thank You! Thank You!

• This worked first time!

  Thanks

• Yes! it works for me. thanks

• This worked for me, THANK YOU!!

• Thanks a lot… It’s worked on my windows 10 too…

• This worked for me. Thanks a lot, you has been a great help for my big headache.

• A modified above worked for me on Win10 2004 (May 2020 update).  I am using WinPro on home pc =no WSUS and therefore no WSUS in registry in AU key.  Unsure as to why people are seeing WSUS enabled in reg or gp on home computers…anyway, I also
  did not have Win10 installation media as it was a digital download upgrade.  I used 7zip to open the downloaded .EXE and found sourcessxs within the «1sources» directory, copied the dotnet3 on demand cab files to  c:sxs then ran the
  dism line above in (powershell as admin) changing the path to the folder I created (c:sxs).  It successfully completed and box checked without having to reboot, although I did for good measure.

  Thank you everyone, except Microsoft, for the solutions provided.

• Вопрос

• Добрый день!

  Появилась необходимость установить на предприятии всем пользователям (около 200 сотрудников) с Windows 10 компонент NetFrameWork 3.5. Доступа в интернет почти ни у кого нет, либо через прокси. Вот что перепробовал:

  — Стандартная .exe установка сообщает, что необходим доступ в MS Update, причём и Offline версия и Online. Соответственно ни чего не происходит, т.к. интернета нет.

  — Включение компонента через «Панель управления» > «Включение или отключение компонентов Windows» так же лезет в интернет.

  — Утилита DISM

  Команда
  DISM /Online /Enable-Feature /FeatureName:NetFx3 /All лезет в интернет конечно же

  Далее копирую с диска папку Sources с компонентами себе на диск C либо просто монтирую образ Windows выполняю команду (от Администратора естественно)

  DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:C:sourcessxs — выдаёт сообщения нет необходимых файлов укажите другой «источник» пробовал и другие файлы, у пары пользователей поставилось, но у подавляющего
  большинства — нет. Давал полный доступ к файлам, переименовывал, подкидывал по очереди — НЕТ!

  — Пробовал через PowerShell

  Команда для установки пакета Enable-WindowsOptionalFeature -Online -FeatureName «NetFx3» -Source C:sourcessxs — ошибка

  Указал принудительную установку пакета dism /online /add-package /packagepath:c:sourcessxs — ошибка Сбой пакета Microsoft-Windows-NetFx3-OnDemand-Package мог произойти из-за ожидающих обновлений служебных компонентов образа. Повторите команду.Команда выполнена с ошибками.
  Дополнительные сведения см. в файле журнала.

  Полный ноль, в очередной раз разочаровываюсь в кривом ПО от Microsoft, в очередной раз уходят дни на копания и устранения бесконечных косяков! Мне нужно ещё загнать всё в GPO, а куда копать уже непонятно.

  Что посоветуете?
