Crack? 7 isn't working as planned.

Hmm... you can use an VLK key, it's more handy than using cracks

P.S: If you don't mind about disabling WU, of course :P

I use a VLK and I run a fully updated XP Pro SP3 with WU enabled and configured to prompt me about updates but not automatically download or install them. It also passes validation checks, but I deny WGA every time it pops up in WU. I don't need or want some piece of shit software checking to see if I'm running genuine windows.
