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:

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

  1. This will open the "Run" program from which you can access your PC's registry.
  2. [1]

  3. Doing so will launch the Registry Editor tool.
  4. 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.
  5. 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]
  6. 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).
  8. [4]
  9. [5]
  10. Don't expand this one. You should see its contents listed in a window on the right side of the Registry Editor page.
  13. These should be several pairs and sequences of random numbers.
  14. This should remove the values listed here.
  15. 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).
  16. This will save your changes.
  18. Remember, you can hold ⊞ Win and tap R to do so.
  19. 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. 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.
  23. This is at the bottom of the "Activate" window.
  24. 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.
  25. 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. 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.
  28. 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

PDF download Download Article
  1. Open the Winkey Finder website . Winkey Finder is a free, no-install program that can locate and retrieve your Windows XP product key.
  2. 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.
  3. You should see this button at the bottom of the Winkey version page.
  4. It should be wherever you chose to save it when you clicked Download (e.g., your Desktop).
  5. Doing so will extract the locked file's contents onto your desktop.
  6. This is the one you just extracted.
  7. It should be the only executable (".exe") file in this folder.
  8. 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.

  5. Exclude the quotation marks.

    • You may need to wait for a minute or so before the window comes up.
