Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Umm, it seem someone did not bother to read the rules.. If your copy of windows is legit, yea, eh, um, then reinstall, use your legit key and then activate by phone.. If not, the above poster has pointed out one of many ways to get legit.. I'll point out another. http://www.newegg.com/Store/SubCategory.aspx?SubCategory=368&name=Operating-Systems
NONE of the XP activation "cracks" work anymore... at least not by themselves.
I had found a very elaborate multi-step process to "crack" the activation in XP a while back (yes I do run legit software)... and I did not distribute it.... it worked great for a few months and then Microsoft changed other stuff (adding the validation required stuff to download certain things) and it didn't work anymore.
If your software is legit.. activate it over the Internet. If it can't activate it over the Internet.. use the phone method to activate it.
