Good tip Fizz, I try to avoid driver install error by keeping this box checked, not all drivers have passed the microsoft ‘genuine driver’ test and this will warn users if they are worried about this happening, alternatively you can check the block option, graphics drivers are the worse ones if they go wrong.
If you are worried however about messing with drivers after a bad install/uninstall a system restore in XP or Vista will take care of this, if you have WY2K re-booting to LKGC (last known good configuration)using the install disc is the other option
Happy Days!
