Vista Time Travel
/I love it when systems are designed to accommodate my own stupidity. Like when I half remove a bunch of camera drivers, fully install the new ones and then find that, not surprisingly, things don't work any more.
Previously there would have been a lot of cursing and muttering and attempts to get the system back to a "known good state" (i.e. before I started fiddling with it).
But with Vista I just fire up the recovery menu and step back in time to the good old days, when things worked, and try again. And I made an interesting discovery, which is that if I don't do stupid things it works a lot better....
