How to change path in windows

How to set the path and environment variables in Windows

Setting the path and environment variables differs depending on the version of the Windows operating system you have on your computer. Choose a link below for your version of Windows.

Administrator privileges are usually required to modify the path and environment variables.

Setting the path and variables in Windows 10

You can edit other environment variables by highlighting the variable in the System variables section and clicking Edit. If you need to create a new environment variable, click New and enter the variable name and variable value.

To view and set the path in the Windows command line, use the path command.

Setting the path and variables in Windows 8

You can edit other environment variables by highlighting the variable in the System variables section and clicking Edit. If you need to create a new environment variable, click New and enter the variable name and variable value.

To view and set the path in the Windows command line, use the path command.

Setting the path and variables in Windows Vista and Windows 7

You can edit other environment variables by highlighting the variable in the System variables section and clicking Edit. If you need to create a new environment variable, click New and enter the Variable name and Variable value.

To view and set the path in the Windows command line, use the path command.

Setting the path and variables in Windows 2000 and Windows XP

The path is now managed by Windows 2000 and Windows XP and not the autoexec.bat or autoexec.nt files, as was done with earlier versions of Windows. To change the system environment variables, follow the steps below.

You can edit other environment variables by highlighting the variable in the System variables section and clicking Edit. If you need to create a new environment variable, click New and enter the Variable name and Variable value.

To view and set the path in the Windows command line, use the path command.

What is the default Windows %PATH%?

The path is based on programs installed on the computer, so there is no «default path.» However, the Windows minimum path is often the path below.

Keep in mind that as you install programs, the path is updated with the paths for the newly installed programs. So, if you have erased your path after installing other programs, those programs may be affected.

Setting path in the MS-DOS and Windows command line

To view and set the path in MS-DOS and in the Windows command line, use the path command.

Set PATH and other environment variables in Windows 10

In older windows systems you had to navigate to Advanced System Settings in Control Panel to view, edit or add environmental variables.

In Windows 8 and 10, you can navigate to Advanced System Settings in a similar way.

However, in Windows 10 you can directly get to the Environment Variables window using Search the web and Windows box next to the Start menu. Type environment variables in Windows Search box which gives you two options in search results:

Choose either option and you can add, edit or delete environment variables like PATH.

Set environment variables from command prompt

You can set environment variables from Windows Command Prompt using the set or setx command. The set command only sets the environment variable for the current session. The setx command sets it permanently, but not for the current session. If you want to set it for current as well as future sessions, use both setx and set.

For example, you can set the PATH environment variable permanently (current and future sessions) as below:

To view the current path, run:

Set environment variable by Registry edit

If your PATH variable is too long, then the best method would be to edit the registry.

Add, Edit or Delete the environment variable you want to change, then reboot to activate the changes.

Set path from command line

Users can run an executable from windows command prompt either by giving the absolute path of the file or just by the executable file name. In the latter case, Windows searches for the executable in a list of folders which is configured in environment variables. These environment variables are as below.

1. System path
2. User path

The values of these variables can be checked in system properties( Run sysdm.cpl from Run or computer properties). Initially user specific path environment variable will be empty. Users can add paths of the directories having executables to this variable. Administrators can modify the system path environment variable also.

How to set path from command line?

In Vista, Windows 7 and Windows 8 we can set path from command line using ‘setx’ command.

For example, to add c:dir1dir2 to the path variable, we can run the below command.

Alternative way is to use Windows resource kit tools ‘pathman.exe‘. Using this command we can even remove a directory from path variable. See download windows resource kit tools. This works for Windows 7 also.

Add directory to system path environment variable:

Open administrator command prompt
Run the below command

Remove path from system path environment variable:
Run the below command from elevated command prompt

Setting user path environment variable

For user environment varlables, admin privileges are not required. We can run the below command to add a directory to user path environment variable.

To remove a directory from user path, you can run the below command.

Default option is not allowed more than ‘2’ time(s)

You get this error if you have not enclosed ‘path’ in double quotes. See the below example for setting the path of firefox.

Now if you move %path% to be in the double quotes

Could a context entry be created for folders, perhaps an extended one… to add to path?

what about a multi-verb option, like copy as path?

Answer: Try add the parameter /M

Hi, is there a way I can add an extra variable instead on deleting the currently one and put a new Variable on the Path.

Nuno, pathman described above does exactly that. You can download the resource tools kit and get it.

setx path “%path%;C:yourFolder”

To set path for java & javac, can I add the paths to PATH or do I need to create the environment variable JAVA_HOME. I don’t have this defined, but windows does not seem to be able to find java binaries on my system.

You can directly add the folder to PATH. No need to define JAVA_HOME. However, adding JAVA_HOME separately avoids cluttering and helps to easily understand what is added.

hello, can someone plz explain this result? After setting path, it did not change. This was run from an Administrator command-line:

C:Windowssystem32>setx path “C:Windowssystem32;C:Windows;C:WindowsSystem32Wbem;C:WindowsSystem32WindowsPowerShellv1.0;C:ProgramDatachocolateybin;D:Program Files (x86)Microsoft VS Codebin”

SUCCESS: Specified value was saved.

C:Windowssystem32>path
PATH=C:Windowssystem32;C:Windows;C:WindowsSystem32Wbem;C:WindowsSystem32WindowsPowerShellv1.0;C:ProgramDatachocolateybin;D:Program Files (x86)Microsoft VS Codebin;D:Program Files (x86)metapad36;D:Program Files (x86)metapad36″ /M

Why won’t this work?

SET EPO = D:Program Files (x86)McAfeeePolicy Orchestrator
PATH = %PATH%;%EPO%jrebin;%EPO%apache2bin

In windows 10 set path %path%; not working. it’s work like :
setx “%path%;C:Program FilesCodeBlocksMinGWbin”

By unfortunately I deleted my system default path. How could I able to find my system path?

Unfortunately I deleted several files with unremembered path names. This article was useful

The following used to work for me when I am in MSDOS environment. Lately I get error messages such as INCLUDE not found. Why is this so?

Used to work
SET PLL =c:CL5PLL
SET PLT =c:CL5PLL
SET INCLUDE =c:CL5INCLUDE
SET PRG =c:IMSPRG
SET LIB =c:CL5LIB
SET OBJ =c:CL5OBJ
PATH =c:IMSEXE;CL5BIN;CL5NG;CL5PLL

pathman is one of many tools of the Windows Server 2003 Resource Kit Tools

Note: The Windows Server 2003 Resource Kit Tools are not supported on 64-bit platforms.

Huh.
When I did that on Windows 10 v1903, using setx, it replaced the USER scope paths with the SYSTEM scope paths.
Now I’m not sure what was in the old user path.
So, uh… Be careful out there.
And if anyone has a solution how to avoid that, please let me know
Thanks

How do I set system environment variables in Windows 10? [duplicate]

How do I set a system environment variable in Windows 10 (without using the registry editor)?

9 Answers 9

PowerShell method

There are different ways to work with environment variables and certain quirks with them in PowerShell so consult the link for details.

Old method (no longer available in newer Windows 10 updates, use PowerShell or see other answers)

Go into Settings and click on System.

Then on the left side click About and select System info at the bottom.

In the new Control Panel window that opens, click Advanced system settings on the left.

Now in the new window that comes up, select Environment Variables. at the bottom.

Still the same as ever: It’s in the old-style control panel’s “System” thingy. You can reach it with Win Break or by right-clicking the Start button.

From there, select “Advanced system settings” → “Environment Variables”.

Or you can do it the hard way and find some other entry point to the old-style control panel, like the Network and Sharing Center or the Desktop folder(!).

I typed «envir» in the «Search the web and Windows» box and selected «Edit environment variables for your account» under the «Best Match»

If by «system environment variables» you refer specifically to system-wide environment variables, then other answers have already covered this. However, if you want to edit both system-wide and user-specific environment variables then most (if not all) of these answers are inapplicable in general case.

If you attempt do that from a regular user account, then trying to access “Advanced system settings” will trigger an UAC prompt asking you for administrator password. If you enter the password, “Advanced system settings” will successfully open, but any user-specific changes you make there will apply to the corresponding administrator’s account (!), not to your original user’s account.

In order to solve this problem (i.e. in order to give regular users the opportunity to edit their own environment variables) Windows provides another way to access the “Environment Variables” dialog.

Open Control Panel. Open User Accounts applet. On the left-hand side of that applet you will see a link that says Change my environment variables. Click that link, and it will take you to the same “Environment Variables” dialog for your user’s environment variables.

If your user has administrator rights, you will be able to edit both sections of that dialog: user-specific environment variables (upper section) and system-wide environment variables (lower section). If you don’t have administrator rights, you will only be able to edit the upper section: your own user-specific environment variables.

This is the proper way to edit environment variables in all post-UAC versions of Windows, not what is suggested in the majority of the answers above.

Unfortunately, Windows 10 November update (version 1511) destroyed this functionality. The Change my environment variables link no longer works. It is there, but it is dead. So for the post-November version of Windows 10 the correct answer is: it is generally impossible to edit user-specific environment variables in version 1511 of Windows 10 from regular user accounts. Microsoft has destroyed Windows 10 with this update and Windows 10 is now unusable. It will remain the case until they fix these ridiculous bugs in 1511 version of the OS.

An alternative workaround is to use PowerShell features as described here https://technet.microsoft.com/en-us/library/ff730964.aspx

Windows 10 Anniversary Update (version 1607) released August 2, 2016 finally fixed this bug.

Adding a directory to the PATH environment variable in Windows

I am trying to add C:xamppphp to my system PATH environment variable in Windows.

I have already added it using the Environment Variables dialog box.

But when I type into my console:

it doesn’t show the new C:xamppphp directory:

I have two questions:

20 Answers 20

Option 1

After you change PATH with the GUI, close and re-open the console window.

Option 2

This option only affects your current shell session, not the whole system. Execute this command in the command window you have open:

WARNING: This solution may be destructive to your PATH, and the stability of your system. As a side effect, it will merge your user and system PATH, and truncate PATH to 1024 characters. The effect of this command is irreversible. Make a backup of PATH first. See the comments for more information.

Don’t blindly copy-and-paste this. Use with caution.

You can permanently add a path to PATH with the setx command:

You should run this command from an elevated command prompt.

If you only want to change it for the current session, use set.

This only modifies the registry. An existing process won’t use these values. A new process will do so if it is started after this change and doesn’t inherit the old environment from its parent.

You didn’t specify how you started the console session. The best way to ensure this is to exit the command shell and run it again. It should then inherit the updated PATH environment variable.

You don’t need any set or setx command. Simply open the terminal and type:

This shows the current value of PATH variable. Now you want to add directory to it? Simply type:

If for any reason you want to clear the PATH variable (no paths at all or delete all paths in it), type:

Update

Like Danial Wilson noted in comment below, it sets the path only in the current session. To set the path permanently, use setx but be aware, although that sets the path permanently, but not in the current session, so you have to start a new command line to see the changes. More information is here.

To check if an environmental variable exist or see its value, use the ECHO command:

I would use PowerShell instead!

To add a directory to PATH using PowerShell, do the following:

To set the variable for all users, machine-wide, the last line should be like:

In a PowerShell script, you might want to check for the presence of your C:xamppphp before adding to PATH (in case it has been previously added). You can wrap it in an if conditional.

So putting it all together:

Better still, one could create a generic function. Just supply the directory you wish to add:

You could make things better by doing some polishing. For example, using Test-Path to confirm that your directory actually exists.

Safer SETX

Warnings

The ss64 SETX page has some very good examples. Importantly it points to where the registry keys are for SETX vs SETX /M

Usage instructions

Append to User PATH

Append to System PATH

(It’s basically the same except with a different Key and the SETX /M modifier.)

Alternatives

Finally there’s potentially an improved version called SETENV recommended by the ss64 SETX page that splits out setting the user or system environment variables.

Example

Here’s a full example that works on Windows 7 to set the PATH environment variable system wide. The example detects if the software has already been added to the PATH before attempting to change the value. There are a number of minor technical differences from the examples given above:

1. Not strictly true

Handy if you are already in the directory you want to add to PATH:

It works with the standard Windows cmd, but not in PowerShell.

Aside from all the answers, if you want a nice GUI tool to edit your Windows environment variables you can use Rapid Environment Editor.

Try it! It’s safe to use and is awesome!

To override already included executables;

It does things in an intuitive way. For example:

It shows results without the need to spawn a new cmd!

Regarding point 2 I’m using a simple batch file that is populating PATH or other environment variables for me. Therefore, there is no pollution of environment variables by default. This batch file is accessible from everywhere so I can type:

Checking the above suggestions on Windows 10 LTSB, and with a glimpse on the «help» outlines (that can be viewed when typing ‘command /?’ on the cmd), brought me to the conclusion that the PATH command changes the system environment variable Path values only for the current session, but after reboot all the values reset to their default- just as they were prior to using the PATH command.

On the other hand using the SETX command with administrative privileges is way more powerful. It changes those values for good (or at least until the next time this command is used or until next time those values are manually GUI manipulated. ).

The best SETX syntax usage that worked for me:

The PATH keyword that follows the SETX defines which set of values should be changed among the System Environment Variables possible values, and the %PATH% (the word PATH surrounded by the percent sign) inside the quotation marks, tells the OS to leave the existing PATH values as they are and add the following path (the one that follows the split sign ‘;’) to the existing values.

Sorry for the long answer, but a short answer on your question is impossible.

First of all you should understand how environment variables works. There are some places in the registry like HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment and HKEY_CURRENT_USEREnvironment where the environment variables will be hold. On start-up the operation system reads this registry keys. Then one windows process creates another windows process. The parent process can give to the client process any set of environment variables. If the parent process doesn’t do this, the child process inherits environment variables of the parent processes.

To be able update environment variables of a running process with respect of WM_WININICHANGE or WM_SETTINGCHANGE messages. A windows application can interpret this messages and reread the current environment variables from the registry HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment and HKEY_CURRENT_USEREnvironment. So you can in general change registry values under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerEnvironment or HKEY_CURRENT_USEREnvironment and send

SendMessage (HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM)"Environment");

It would be much better to use SendMessageTimeout instead of SendMessage, but the idea will stay the same. The problem is that other processes must not wait for the message and do something. Most console application have no message loop and don’t do anything if you send such messages.

So it is important to understand that there is no simple way to update environment variables of all processes without restarting of the computer. You should have a clear understanding of this and reduce your question a little.

If you update the environment in registry and send SendMessage (HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM)"Environment") then new processed created by Explorer.exe will be have new environment variables, but cmd.exe will not do this.

If you want to update environment variables of the current cmd.exe inside a batch run you can do the following: You can create a new CMD file for example t.cmd in %TEMP% directory, write in the file SET PATH=%PATH%;C:BlaBla and then use call %TEMP%t.cmd and dell %TEMP%t.cmd to update environment variables of the current cmd.exe.

To be exactly there are more places which are used to build environment variables of new created processes. This are subkeys of the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionApp Paths and %SystemRoot%System32autoexec.nt file. One will be used for processes created by ShellExecute and ShellExecuteEx (for example Explorer.exe) and another for console applications.
