Will Vistaloader or Wow work in MS Virtual PC Quick question before I attempt. I am running Vista64 Ult with Bios upgrade. I am also using MS Virtual PC with Vista32 that needs activation. Can I just use Vistaloader or Wow (suggestions?) to activate the VPC of vista32,sp1, or will that screw up my main os which is Vista64, sp1. I would hate to try this and find out that even though I was in a MS Virtual PC, the activator changed my main system information.
