If you look at how things are run in corporate IT, you save your important data to the network servers .... if something happens you don't waste more than a limited amount of time trying to diagnose the issue. If you can't solve it, its wipe clean and start fresh. Wasting time on desktop issues is the most pointless thing known to man kind.
Precisely what I have been saying?? Windows update stuffed my system. I did a complete rollback to the previous night's image. I was operational in 30 minutes. You're suggesting that I re-install Windows. You're nuts.
