I've put Vista back to Win98 look the moment I got my hands on them. There's still a lot of stuff I don't like about it, like not being able to log into the nick Administrator, or being able to download files to C:\ root.
If I didn't need Vista for hardware support, I would so not be running it. Yes, there's stuff on the core that's better than earlier versions of windows, but seriously, it's MY computer, not my OS's, and I hate the amount of control the OS takes and forbids me to take myself.
As for the user control, the moment you pop that, you'll have to live with that red shield at the bottom right of your screen for the rest of eternity.
