Steps:

1. Click on Start>My Computer.
2. Type the following text into the address bar at the top of the page C:\WINDOWS\system32
3. Locate the file called WgaTray or WgaTray.exe and click on it once.
4. Press the shift+delete keys (this combination will autmoatically delete the files completely off your PC instead of to the Recycle Bin) but don’t confirm the deletion yet.
5. Right click on a non-occupied area of the taskbar and select Task Manager.
6. Click on the Processes tab at the top.
7. Select the process called WgaTray.exe and click the end process button at the bottom and click yes to confirm the process termination.
8. Confirm the delete of the WgaTray that you semi-deleted earlier (this must be done almost immediately after the process termination because it will re-open itself quickly so it’s a good idea to have the deletion confirmation window open behind the task manager for fast access).
9. Restart your PC.
10. In the system32 folder that was opened earlier, find and select the file called WgaLogon.dll and drag it into the Recycle Bin (located on the Desktop).
11. Empty your Recycle Bin.
12. Restart your PC and the Windows Genuine Advantage Notifications Tool shouldn’t run anymore so now you have completely hassle free Windows XP usage.

    Things You'll Need:

    • Microsoft Windows XP & Windows Genuine Advantage Notifications Tool (hopefully not for long).
