I was on 6.10.10.0, got the upgrade message, assumed it would TELL ME ABOUT IT and the thing went ahead and installed 7, without mentioning the large upgrade expense. After a considerable struggle, I got 6.10.10.0 re-installed, but now the password for every single customer computer is gone. This is going to cost me roughly 18 hours to repair, while disrupting every support call for the next who-knows how long.
