gsandan Posted February 5, 2008 Share Posted February 5, 2008 If I toggle UAC on after Vista asks me to reboot to apply the changes, I get a black screen with only the mouse. I can do a CTRL + ALT + DEL but, Vista won't let me into the task manager to execute EXPLORER.EXE. WIN + R does not work either so, I can't start EXPLORER.EXE.Anybody have any ideas?

gosh Posted February 5, 2008 Share Posted February 5, 2008 Well vista uses a driver for UAC, so, enable boot logging and see what the last service was loaded. You could try sfc /scannow (if that still exists in vista) or repair vista-gosh Link to comment Share on other sites More sharing options...
cluberti Posted February 5, 2008 Share Posted February 5, 2008 It's actually switching the desktop window to the session 0 window (to allow you to see the UAC prompt), and a good test is to boot into safe mode (VGA) boot, and see if it does the same thing. If so, then sfc /scannow is definitely a good move. If it doesn't, however, you've got a driver (video) problem... Link to comment Share on other sites More sharing options...
gsandan Posted February 6, 2008 Author Share Posted February 6, 2008 I can boot into safe mode without any problems. I tried the low resolution boot and still nothing.Also did a sfc /scannow, and still nothing.Any other ideas? (Does UAC depend on a service) Link to comment Share on other sites More sharing options...
