How to Activate Windows XP Without a Genuine Product Key

Written by Jack Lloyd

Last Updated: May 9, 2023 Fact Checked

This wikiHow teaches you how to bypass the trial version of Windows XP, either by using a stock product key or by using software to display your own product key. Note that you should only use the following information if you are unable to activate even though you have a legally-purchased copy of Windows XP.

Note: The three methods presented here may need to be used together depending on the situation:

Changing the Windows XP Product Key Manually - includes instructions for how to use a stock product key to activate Windows XP.
Using the Windows Key Finder - provides the detailed steps to get the product key from your device using Windows Key Finder.
Fixing the Windows Activation Loop - is only required if you have already reached the time limit for activation and need to reset the loop.

Method 1 of 3:

Changing the Windows XP Product Key Manually

This will open the "Run" program from which you can access your PC's registry.

Doing so will launch the Registry Editor tool.

Review the options tree on the left side of your screen. You'll need to navigate through several of the folders listed here in order to reach your destination.^{[2]

- Since the registry holds most of your computer's sensitive system information, consider clicking File and then Export in the top left corner of your screen to back up your registry before proceeding.
Note that you'll need to click the + sign to the left of the folder to expand it--don't click the folder itself.^{[3]

Each folder you need to expand after this point will be inside of the previous folder (for example, "SOFTWARE" was inside of "HKEY_LOCAL_MACHINE" and so on).

Don't expand this one. You should see its contents listed in a window on the right side of the Registry Editor page.
These should be several pairs and sequences of random numbers.
This should remove the values listed here.
It doesn't matter what you put here, but you'll need to keep the format consistent (for example, if you deleted four characters, you'll need to replace that section with four characters).
This will save your changes.
Remember, you can hold ⊞ Win and tap R to do so.
$Step 19 Type "%systemroot%\system32\oobe\msoobe.exe /a" into the Run window.$

19
Type "%systemroot%\system32\oobe\msoobe.exe /a" into the Run window. Exclude the quotation marks. Entering this command opens the Windows XP activation wizard.
- For best results, simply copy and paste this text into the Run field.
21
Select the telephone option. This option should say "Yes, I want to telephone a customer service representative to activate Windows" and there should be a clickable check box to the left of it.
- If you see a note that says "Windows XP is already activated", changing your key manually isn't working. Please proceed to the Windows Key Finder method.
This is at the bottom of the "Activate" window.
24
Enter a Windows XP product key. Note that you may have to attempt this step a few times with different keys.
- If you don't know the version of Windows XP your computer is currently running, consult your computer's manual to verify before you proceed with trying the linked product keys.
This will generate a new Windows XP ID for your computer. After this process completes, you'll need to confirm your activation of Windows XP.
27
Check the "Activate Windows over the Internet" option. This will allow you to activate your version of XP quickly.
- Note that calling Microsoft using the "telephone a customer representative" option likely won't work since Microsoft discontinued support for Windows XP on April 8th, 2014.
After you've completed your Windows XP activation, you should be able to use it without getting locked out of the system.

Method 2 of 3:

Using the Windows Key Finder

Download Article

Open the Winkey Finder website. Winkey Finder is a free, no-install program that can locate and retrieve your Windows XP product key.
2
Click on the latest version of Winkey Finder. As of January 2017, this is version 2.0.
- Since this version is currently in beta, you can also download the final version of 1.75.
You should see this button at the bottom of the Winkey version page.
It should be wherever you chose to save it when you clicked Download (e.g., your Desktop).
Doing so will extract the locked file's contents onto your desktop.
This is the one you just extracted.
It should be the only executable (".exe") file in this folder.
8
View your product key. Running the Winkey Finder program should immediately display your Windows XP product key, allowing you to apply the key to the Windows XP activation wizard the next time Windows asks you to update.
- To be safe, be sure to write down the product key when you see it.

Fixing the Windows Activation Loop

Download Article

You can choose this option from the Start menu, or you can simply hold down your computer's power button until it turns itself off and then press the button again.
2
Tap F8 as soon as your computer logo appears. You'll need to do this during the first time the logo appears after rebooting.
- Keep tapping F8 until you see the advanced options menu pop up.
Starting up your computer in this mode will bypass the Windows activation loop long enough for you to reset the timer for your XP trial.
You'll need to wait a minute or so for Safe Mode to load.
Exclude the quotation marks.
6
Tap ↵ Enter. You should see a dialogue window pop up after doing so.
- You may need to wait for a minute or so before the window comes up.
This may also say OK. After doing so, you should notice that your desktop interface is now accessible.
This will bring up the Run tool from which you can complete the fix.
This command resets the Windows XP trial clock to 30 days.
When your welcome screen finishes loading, you should be able to log in like usual rather than being stuck in the activation loop.

Question

Can I do this more than once? I have already done the 30 days one, a.k.a. Step 3. Nothing I do is working this time around.

Community Answer

You can only rearm the timer up to four times while in the grace period, or two times in safe mode.
