i have had a vista (home premium) machine since april 2008. yes, i found the user access control very annoying, but since i hadn't been able to install an anti-virus (i only had dial-up at home, and VHP doesn't seem to allow access to the net via a firewall that is my work) i kept it on and put up with it.
now, several months later, i barely notice it b/c i have my comp configured the way i like it. i quite like the new look. and i haven't had any problems at all with it.
the only gripe i DO have, is that i can't see progress on the Disk Defragmenter like in previous versions of windows.... it's just one little dialog box, no progress bar, now defrag details... does anyone know how to access the details again in vista?
