Vista Deactivated by Installing / Running Programs

growse writes: "It seems that even the most every day tasks can cause Vista to deactivate itself and require reactivation. Ed Bott has written about his experiences with such issues and includes a screenshot gallery of what the user experiences when Vista decides to deactivate itself. Microsoft has a support document about the issues here.

Is this an indication of more anti-piracy screwups to come? It seems that we're past the point of anti-piracy measures being only inconvenient for pirates, so now that legitimate users are being affected will they start to look for other OS options?"
