I am running Windows XP SP2 on an old PC for my families internet. Two days ago it prompted that I had three days left to re-validate Windows due to 'Significant hardware changes'. My issue is, I know for a fact that I have not made any hardware changes since I installed windows three years ago.
My concern is that this is not a legitimate Windows prompt and may be some form of phishing malware trying to get my CD-Key. It still says I have three days left to revalidate which adds evidence to this theory.
Does anyone know why Windows would need re-validating? Is there any malware that would account for this behaviour?
