You’ve installed your OS or entered your product key, but now you want to change it. How do you do it? You can use the Windows Activation Wizard graphical user interface (GUI) or a Windows Management Instrumentation (WMI) script. The Activation Wizard method is easier, but if you must change the product key for multiple computers, the script method is better.

Question
What should I do if it doesn’t accept the Product Key, even if it is right?

Community Answer
If the product key isn’t working, there is something wrong with the OS. It also might be due to the fact that Windows XP has stopped being supported. You can try updating Windows.

This will not work when the installation source and the product key are representative of varying licenses. For example, if the installation CD is a retail license, but the product key is for an OEM license.
-
Never tell anybody your product key.
-
Editing the registry (or any system file) is like surgery: BE CAREFUL! Don’t edit anything except what this article tells you to when you open, ‘Regedit’. Doing so can cause system instability, changes in functionality, or worse, be unable to use Windows altogether.
-
Do not use any product keys that you find on any websites, these could cause you to fail the windows genuine advantage test as those keys are probable already one Microsoft’s product key blacklists. Failing this test loses your operating systems genuineness, restricts updates and displays annoying messages to buy a real product key.

Do you need to change Windows XP product key so you can activate Windows properly? Sometimes, users are required to change or re-enter the product keys in Windows XP to solve and fix activation problems, or after buying a genuine license for Windows operating system, it’s necessary to reactivate Windows.
However, there is only one chance for you to enter your product key during Windows XP installation. How to change Windows XP product key after install? Here are a few simple steps for you to change your Windows XP product key in order to activate existing copy of Windows XP.
How to Change Windows XP Product Key After Install?
- Click Start, and then click Run.
- In the Open box, type regedit, and then click OK.
- In the left pane, locate and then click the following registry key:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrent VersionWPAEvents
- In the right pane, double-click OOBETimer, then change at least one digit of this value to deactivate Windows.
- Click Start, and then click Run.
- In the Open box, type the following command, and then click OK.
%systemroot%system32oobemsoobe.exe /a
- When the Windows Product Activation window appears, choose Yes, I want to telephone a customer service representative to activate Windows and then click Next.
- Click Change Product key.
- Type the new product key in the New key boxes, and then click Update.
Reboot your computer and Windows XP is already activated. So here is how can you change Windows XP product key after install. To update your product key doesn’t really require whole fresh re-installation of Windows XP.
Tips: If you’ve lost or misplace your Windows XP product key, you can easily recover it from your current genuine Windows XP installation using Product Key Finder.

For most Windows XP installs, you’ll never need to worry about the validity of the product key assigned to your copy of the OS. However, software does tend to get installed without authorization, even in the most carefully managed shops, and so from time to time you may need to reset the XP product key.
For example, perhaps a user installed a pirated copy of XP but now wants to go legal. Maybe you’ve been hired by an organization that installed 100 pirated copies of XP but now has a legitimate volume-licensing key (VLK). Perhaps an end user purchased an additional retail license for XP but needs to use his original CD to install the software. When situations like these arise, changing XP’s product key is often the most practical—or only—solution.
Determining if you have a valid product ID
Hopefully you already know if you’re dealing with a pirated copy of XP. But if you’re unsure, a quick way to tell is to install Service Pack 1. Shortly after releasing Windows XP, Microsoft realized that most pirated XP installations were using two specific VLKs, the most popular of which begins with “FCKGW.” These VLKs produce product IDs that match either XXXXX-640-0000356-23XXX or XXXXX-640-2001765-23XXX, where X is any number.
If you try to install SP1 and get the following error message:
The Product Key used to install Windows is invalid. Please contact your system administrator or retailer immediately to obtain a valid Product Key…”
You are dealing with a pirated copy of Windows. For more information about obtaining a valid product key, see Microsoft Knowledge Base article 326904.
You can also directly check the OS’sproduct ID by right-clicking on My Computer, clicking Properties, and selecting the General tab. The machine’s product ID will be located under the Registered To section. If the ID matches either of the two models commonly associated with VLK fraud, you’ll need to obtain a valid XP product key before proceeding. None of the procedures described below will work without a legitimate product key.
Two methods of changing Windows XP’s product key
You can change a Windows XP installation’s product key either by editing the registry or by using one of two Windows Management Instrumentation (WMI) scripts. The registry editing method is outlined in Knowledge Base articles 321636 and 328874 and works on Windows XP Home, Windows XP Professional, and Windows XP Corporate Edition. The script method is outlined in article 328874 and is designed to work on Corporate Edition installations that use a VLK and do not require activation. It may work on a Home or Professional installation, but I have not tested this scenario.
The script method is the practical solution for changing the product keys on a large number of machines. Regardless of the method you choose, make sure to backup important data before changing a product ID, since an unexpected problem could render the machine unbootable and necessitate a complete reinstallation of Windows.
Warning
The following instructions involve editing your system registry. Using the Windows Registry Editor incorrectly can cause serious problems that require the reinstallation of your operating system and possible loss of data. TechRepublic does not support problems that arise from editing your registry. Use the Registry Editor and the following directions at your own risk.
Editing the registry
Begin by opening the Registry Editor and navigating to
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsNTCurrent VersionWPAEvents
In the right pane, right-click the ODBETimer binary value and select Modify. Change at least one character of this value to either a number from 0 to 9 or to a letter from A to F, then click OK and close the Registry Editor. This renders the current product key invalid and deactivates Windows.
Now, it’s time to reactivate Windows using your new product key. Click Start | Run and enter the command:
%systemroot%system32oobemsoobe /a
where %systemroot% is your Windows directory. In many cases, this command will look like:
C:windowssystem32oobemsoobe.exe /a
At this point, Windows will launch the Product Activation Wizard.
Figure A |
Select the option to telephone a Microsoft customer service representative to activate Windows, as shown in Figure A, and click Next. Now, select the Change Product Key option and enter your new product key as shown in Figure B. Finally, click Update and close the window. If Windows returns you to the previous screen, just select the Remind Me Later option. When the wizard is finished, reboot the system.
Figure B |
When Windows reboots, your next step will depend on which Windows XP version you are using. If you have XP Home or Professional, you’ll be prompted to reactivate your copy of Windows through the normal activation process. If you have XP Corporate, no activation is required and your machine should have a valid product ID. You can verify this by running the %systemroot%system32oobemsoobe.exe /a command again. When the wizard loads this time, you should see a message indicating that your copy of Windows has already been activated.
Using a WMI script
Although the registry editing process is effective, it can be tedious and impractical if you need to change the product key on more than a few machines. So Microsoft provides two WMI scripts, one for XP machines with SP1 and one for XP machines without SP1.
View the code for the WMI script, ChangeVLKey2600.vbs, designed for use on XP machines without SP1.
View the code for the WMI script, ChangeVLKeySP1.vbs, for XP machines with SP1 already installed.
Copy the appropriate script’s code into a text file and save it as either ChangeVLKey2600.vbs or ChangeVLKeySP1.vbs. The scripts can act in conjunction with a valid product key as part of a login script to change the product ID on multiple machines. You can also execute the script from the command line to change the key on a single computer.
For example, if you wanted to change the product key on an XP machine without SP1 and had already saved the script to root directory on the C: drive, you would click Start | Run and enter the following command:
C:changevlkey2600.vbs xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Of course, xxxxx-xxxxx-xxxxx-xxxxx-xxxxx in this scenario is a valid product key.
The script should take only a few seconds to run and won’t prompt you for further action unless there’s a problem, such as an invalid product key. As with the registry editing method, you can verify that Windows is now using a valid product key by running the command:
%systemroot%system32oobemsoobe.exe /a
The Product Activation Wizard will load and should tell you that your copy of Windows has already been activated.
How can I change the volume licensing product key on a Windows XP SP1-Based Computer?
Because of changes in Windows XP Service Pack 1 (SP1), Windows XP-based computers that use a leaked product key that is known to be available to the general public may not be able to install SP1 or automatically obtain updates from the Windows Update Web site. For an easy and quick method of obtaining your own CD Key please read Quickly Retrieve Windows CD Key.
For example, you may experience the symptoms that are described in the following Microsoft Knowledge Base article when you install SP1:
326904 Error Message: The Product Key Used to Install Windows Is Invalid
There are two (legal) methods that you can use to change the product key with volume licensing media after installation. You can use either the Windows Activation Wizard graphical user interface (GUI) or a Windows Management Instrumentation (WMI) script.
The easier method to use is the Use the Activation Wizard method. Use this method when you only have a few computers on which to change the product key. The Use a Script method is best when you have a number of computers on which you have to change the product key.
Legal Note: Make sure you understand that this method is indeed legal. This is NO crack, NO hack, there is nothing illegal with this article. I will not, however, encourage any reader to use an illegally obtained CD Key. What you do in your own house/office is your own business, and I cannot and will not be held responsible for your actions.
Method #1: Use the Activation Wizard
If you have only a few volume licensing product keys to change, you can use the Activation Wizard.
Warning!This document contains instructions for editing the registry. If you make any error while editing the registry, you can potentially cause Windows to fail or be unable to boot, requiring you to reinstall Windows. Edit the registry at your own risk. Always back up the registry before making any changes. If you do not feel comfortable editing the registry, do not attempt these instructions. Instead, seek the help of a trained computer specialist.
Note: Microsoft recommends that you run System Restore to create a new restore point before you complete the following steps:
- Click Start, and then click Run.
- In the Open box, type Regedit, and then click OK.
- In the left pane, locate and then click the following registry key:
- In the right pane, right-click OOBETimer, and then click Modify.
- Change at least one digit of this value to deactivate Windows.
- Click Start, and then click Run.
- In the Open box, type the following command, and then click OK.
- Click Yes, I want to telephone a customer service representative to activate Windows, and then click Next.
- Click Change Product key.
- Type the new product key in the New key boxes, and then click Update. If you are returned to the previous window, click Remind me later, and then restart the computer.
- Repeat steps 6 and 7 to verify that Windows is activated. You receive the following message:Windows is already activated. Click OK to exit.
- Click OK.
- Install SP1 for Windows XP.
If you cannot restart Windows after you install SP1, press F8 when you restart the computer, select Last Known Good Configuration, and then repeat this procedure.
Method #2: Use a Script
You can create a WMI script that changes the volume licensing product key, and then deploy this script in a startup script. The sample ChangeVLKey2600.vbs script and the sample ChangeVLKeySP1 script that are described in this section use the new volume licensing key that you want to enter, in its five-part alphanumeric form, as a single argument. Microsoft recommends that you use the ChangeVLKey2600.vbs script on Windows XP-based computers that are not running SP1 and that you use the ChangeVLKeySP1.vbs script on Windows XP-based computers that are running SP1. These scripts perform the following functions:
- They remove the hyphen characters (-) from the five-part alphanumeric product key.
- They create an instance of the win32_WindowsProductActivation class. They call the SetProductKey method with the new volume licensing product key.
You can create a batch file or a CMD file that uses either of the following sample scripts, together with the new product key as an argument, and either deploy it as part of a startup script or run it from the command line to change the product key on a single computer.
ChangeVLKeySP1.vbs
WMI Script - ChangeVLKey.vbs This script changes the product key on the computer *************************************************************************** ON ERROR RESUME NEXT if Wscript.arguments.count<1 then Wscript.echo "Script can't run without VolumeProductKey argument" Wscript.echo "Correct usage: Cscript ChangeVLKey.vbs ABCDE-FGHIJ-KLMNO-PRSTU-WYQZX" Wscript.quit end if Dim VOL_PROD_KEY VOL_PROD_KEY = Wscript.arguments.Item(0) VOL_PROD_KEY = Replace(VOL_PROD_KEY,"-","") remove hyphens if any for each Obj in GetObject("winmgmts:{impersonationLevel=impersonate}").InstancesOf ("win32_WindowsProductActivation") result = Obj.SetProductKey (VOL_PROD_KEY) if err <> 0 then WScript.Echo Err.Description, "0x" & Hex(Err.Number) Err.Clear end if Next
ChangeVLKey2600.vbs
WMI Script - ChangeVLKey.vbs This script changes the product key on the computer *************************************************************************** ON ERROR RESUME NEXT if Wscript.arguments.count<1 then Wscript.echo "Script can't run without VolumeProductKey argument" Wscript.echo "Correct usage: Cscript ChangeVLKey.vbs ABCDE-FGHIJ-KLMNO-PRSTU-WYQZX" Wscript.quit end if Dim VOL_PROD_KEY VOL_PROD_KEY = Wscript.arguments.Item(0) VOL_PROD_KEY = Replace(VOL_PROD_KEY,"-","") remove hyphens if any Dim WshShell Set WshShell = WScript.CreateObject("WScript.Shell") WshShell.RegDelete "HKLMSOFTWAREMicrosoftWindows NTCurrentVersionWPAEventsOOBETimer" 'delete OOBETimer registry value for each Obj in GetObject("winmgmts:{impersonationLevel=impersonate}").InstancesOf ("win32_WindowsProductActivation") result = Obj.SetProductKey (VOL_PROD_KEY) if err <> 0 then WScript.Echo Err.Description, "0x" & Hex(Err.Number) Err.Clear end if Next
Example
The following example describes how to use the ChangeVLKeySP1.vbs script from a command line:
- Click Start, and then click Run.
- In the Open box, type the following command,
where AB123-123AB-AB123-123AB-AB123 is the new product key that you want to
use, and then click OK:
If you discover your current Windows XP key is pirated or illegal but you don’t want to Reinstall Windows XP to activate your new legal key. Before we begin I recommend you to Back up your Registry.
Here’s How:
- Click on Start and then Run.
- In the text box in the Run window, type regedit and click OK. This will open the Registry Editor program.
- Locate the HKEY_LOCAL_MACHINE folder under My Computer and click on the (+) sign next the folder name to expand the folder.
- Continue to expand folders until you reach the HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsNTCurrent VersionWPAEvents registry key.
- Click on the WPAEvents folder.
- In the results that appear in the window on the right, locate OOBETimer.
- Right-click on the OOBETimer entry and choose Modify from the resulting menu.
- Change at least one digit in the Value data text box and click OK. This will deactivate Windows XP. Feel free to close Registry Editor at this point.
- Click on Start and then Run.
- In the text box in the Run window, type the following command:%systemroot%system32oobemsoobe.exe /a and click OK.
- When the Let’s activate Windows window appears, choose Yes, I want to telephone a customer service representative to activate Windows and then click Next.
- Click the Change Product Key button at the bottom of the window.Don’t worry about filling anything out on this screen.
- Type your new, valid Windows XP product key in the New key: text boxes and then click the Update button.
- You should now reactivate Windows XP by following the instructions on the Activate Windows by phone window which you should now be seeing or via the Internet by clicking the Back button and following the instructions on that screen. If you’d rather postpone activating Windows XP until a later date, you can click the Remind me later button.
- After activating Windows XP, you can verify that activation was successful by repeating steps 9 and 10 above. The Windows Product Activation window that appears should say “Windows is already activated. Click OK to exit.”
The Windows Product Activation window that appears should say “Windows is already activated. Click OK to exit.”
Note: Take great care in making only the changes described below. I recommend that you Backup the Registry before any Modifications.

I started this tech blog back in 2011 as a place to write down processes I took to fix my client systems and network. Now I write some tips and tricks to help others with the tech issues that one might encounter.
В мае 2003 года Брайан Пози (Brien Posey) опубликовал статью о том, как изменить ключ продукта (Product Key) в Microsoft Windows XP. Его метод предусматривал редактирование реестра или выполнение специального сценария и был рассчитан на исключительно смелых пользователей. С тех пор разработчики Microsoft уже создали специальный апплет, сделавший процесс смены ключа гораздо проще и безопаснее.
Обратите внимание: чтобы изменить ключ продукта, нужна лицензионная копия Microsoft Windows XP и действительный ключ продукта, поскольку апплет осуществляет проверку подлинности Microsoft, прежде чем разрешить изменение ключа.
Порядок действий
Для начала откройте страницу «Обновление ключа продукта | Выберите версию Windows» (Update Your Product Key: Select Your Version of Windows) на сайте «Подлинное программное обеспечение Microsoft» (Genuine Microsoft Software) (рис. A).
Рисунок A. Откройте страницу «Обновление ключа продукта | Выберите версию Windows»
Внимание: не повторяйте моей ошибки — апплет будет работать гораздо стабильнее, если воспользоваться Internet Explorer.
Нажмите кнопку «Windows XP», чтобы попасть на страницу, показанную на рис. B.
Рисунок B. Инструкция по использованию средства обновления ключа продукта Windows Product Key Update Tool
Внимательно прочитайте предложенные инструкции. Microsoft советует создать точку восстановления — это вообще рекомендуется делать при внесении в систему любых изменений. Обратите внимание на ненавязчивое предупреждение об отправке данных в Microsoft для проверки подлинности системы.
Если вы на это согласны, поставьте флажок «Я понимаю, что данное средство отправит указанную выше информацию в корпорацию Майкрософт» (I understand this tool will send the above information to Microsoft) и нажмите кнопку «Загрузить» (Download). Появится стандартный диалог «Выполнить/Сохранить/Отмена» (Run/Save/Cancel), показанный на рис. C.
Рисунок C. Выберите действие.
Дальше вас ждет уже знакомый интерфейс мастера с привычными инструкциями. Нажмите «Выполнить», чтобы увидеть окно с предупреждением, показанное на рис. D.
Рисунок D. Нажмите «Выполнить».
Подтвердите запуск апплета. Появится окно мастера, показанное на рис. E.
Рисунок E. Окно мастера.
Нажмите «Далее» (Next). Откроется окно для ввода нового ключа продукта (рис. F).
Рисунок F. Введите ключ продукта.
Затем нажмите «Далее» и «Готово» (Finished), чтобы перезагрузить систему. После перезагрузки придется пройти стандартную процедуру активации, чтобы завершить смену ключа продукта.

Дата окончания поддержки Windows XP наступила в начале 2014 года. Нет никаких гарантий, что в 2020 году и далее процесс активации будет работать так, как предполагалось изначально.
Основная причина, по которой вы можете захотеть изменить ключ продукта Windows XP, заключается в том, что ваш ключ пиратский или иным образом неверен, но вы не хотите переустанавливать Windows XP для активации нового легального ключа продукта.
Мы создали это пошаговое руководство в дополнение к нашему оригинальному руководству « Как изменить код ключа продукта Windows XP» . В этом процессе есть несколько очень специфических шагов, многие из которых включают редактирование реестра Windows , поэтому это визуальное руководство должно помочь устранить любую путаницу.
Выберите опцию активации телефона
Окно «Активируем Windows» начинает процесс активации.
Выберите Да, я хочу позвонить представителю службы поддержки, чтобы активировать переключатель Windows , а затем нажать кнопку Далее .
Вы не будете активировать Windows XP по телефону. Это просто шаг, который вы должны сделать прямо сейчас, чтобы попасть в область, где вы можете изменить ключ продукта Windows XP.
Если вы не видите экран выше, но вместо этого видите сообщение, уведомляющее вас о том, что Windows XP уже активирована, возможно, вы неправильно изменили значение OOBETimer, и в этом случае вы должны начать этот процесс заново .
