I am here because every night I run Norton Utilities 15 to clean my Registry. Without fail it always says a High Priority value is missing or invalid. When i click to repair it, it never is repaired. It lists the hexkey followed by "default=%ProgramFiles%\VirtualPC\".
I never use the virtual pc because all my programs seem to work fine in Win 7 64bit. So I tried to activate it,VPC, and when I clicked on it from the start menu it opened a win explorer window to the windows xp folder. I closed that window and went back to the start menu and clicked on windows xp since they were both listed under the same location as windows virtual pc, and clicked it. The virtual pc window opened without problems and shows the tool bar at the top of the window. So far as I can tell it is working fine, but not sure how to truely test it. Still don't know why I always get the above displayed problem with Norton. What opens what is of no particular concern to me as I just created a shortcut on the Desktop using windows xp the renamed it to say Win VPC.
