My brother in law gave my dad his old PC with a legitimate version of Windows XP Home on it. However, when I tried to download Windows Defender for my dad, WGA said it was not a valid product key.
Unfortunately, I did not have time to investigate why the key was not valid or try rectifying it, but I wondered if he should not go online until I or my brother in law get chance to sort out the problem.
I have looked on the microsoft and MGA websites to see if this is a problem and they state that if the product key is not valid then you will not be able to download certain software and updates, however critical updates can still be downloaded. They also state that when going through the validating process no details of name, address or email address are taken.
I was concerned though, because I had heard that if you run what microsoft deems a non valid version of XP then your operating system can be blocked. I looked on this forum and one person said it is not a problem as he has been using the same product key on three PC's (therefore not valid) for years and has never had a problem. Someone else on this forum said that you can get blocked with a non valid key, but it may be within 2 weeks, a month or even after a year.
Does it depend on the reason why your product key is not valid whether you become blocked? (For example, blocked VLK or keygen created as opposed to multiple users.)
