If, when you try to update Windows XP, you get the following error message:
Validation Failure: Invalid Product Key
Do the following to update windows:
1. Open Internet Explorer
2. Click "Tools"
3. Click "Manage Add-ons..."
4. Show "Add-ons that have been used by Internet Explorer"
5. Select "Windows Genuine Advantage"
6. Disable
7. OK
Very intresting, the last time I had to do this work around I used Trixie, an add on for IE. I'll keep this in mind next time, maybe we could start a new fourm index and call it a "Windows Tips and Tricks"
If I could remember all I have forgotten, I would be a smart man.
