I have a Windows XP Pro VLK disk that has worked great for many years but ever since SP3 I always get the genuine activation problem. I have tried Antiwpa but that doesn't work at all anymore. So instead I have to use a VLK keygen, and a key changer and a program that changes the hosts file then a reboot and it works. It is quite a long process. There are so many bypass programs out there and it is too confusing to test each one (most are a virus it seems too!) Any suggestions on what to try would be great and I appreciate the time to respond.
