How to Disable XP Home Activation

By WayneC

Windows XP comes with a requirement that a user "activates" XP when installing it in order to use it. Microsoft says this is to reduce "casual copying," which the company states is sharing and installing software in a manner "not in accordance with the software's end-use license agreement." Basically, the requirement ensures that the copy of XP being installed is legitimate and that it is not being installed more times than permitted. It is possible, however, to disable the activation of XP if a user wishes.

Step 1

Click the "Start" button on the lower left side of the screen. When the Start menu appears, select "Run."

Step 2

Type "regedit" in the Run window and click "OK."

Step 3

Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WPAEvents" and select the "OOBETime" option.

Step 4

Double-click "OOBETime" and change the content of it to "FF D5 71 D6 8B 6A 8D 6F D5 33 93 FD." Right-click on "WPAEvents" and select "Permissions." Click the "System" tab and check everything in the "Deny" checklist.

Step 5

Restart the computer.

Tips & Warnings

  • The copy of XP is no longer recognized as legitimate. This could lead to limited functionality.
