What to do about counterfeit Windows warning
Why should my laptop, (about three years old) now keep telling me that my copy of Windows does not pass Genuine Validation? I have been using regularly since I bought it some three or so years ago, all set up with Windows which I obviously purchased at the time.
The Laptop is a Gateway Laptop, bought from Tesco.
Most likely, the Gateway OEM key was revoked. Re-activate using the COA sticker on the notebook.
