I upgraded to Vista SP1 about a month ago and imeediately after installed the Windows Vista Developer Activation and was able to activate Vista. But today suddenly Vista is asking me to activate... and that too today. The last updates that I installed were Update for Microsoft XML Core Services 4.0 Service Pack 2 (KB941833), Windows DreamScene, Hold Em Poker Game, and Windows Sound Schemes. Has MS hidded the crack disabler in these updates? This was on the 24th, almost five days ago, so what did I do taht made my Vista ask for activation? IS there another crack that works with SP1. Appreciate any help.
