I held the door open today for an engineer who was carrying out a PC tower. Apparently, the Avid software had deleted Windows.

I'm sorta with Bittmann on this one, and further would say that thats a plain crock ito factual correctness and possibility for the simple fact that, for Avid to be able to run and cause the supposed disaster it needed Windows to be present .......................... at worst Avid software may somehow have been able to damage some OS file/s - it cannot "delete Windows"  ......................  IMO anyway
