mine for the following reason: Besides the annoyance, it allows a standard user to open mmc, regedit, services, et. al. without ANY prompt and an administrator can't even look at the UAC setting without confirming credentials!!! Why does an administrator have to confirm credentials to open a regedit or mmc session while a standard user gets no prompt?!?!? BTW, I have Vista Home Premium 64-bit SP1 *ONLY* because Dell did not give me any other option. Another brilliant POS version of Microsnot Winblows. Putting the slider does not disable it completely. It just says do not notify me. I am having issues with programs not performing correctly until I select 'run as administrator'. I am already an administrator and my slider is at the bottom. What we need is the ability to disable it COMPLETELY, not make it silent. I just bought a new notebook with vista home edition pre-installed and followed these instructions to stop UAC. When the notebook rebooted after turning off UAC, a lot of important services had also been automatically disabled by Vista. This included ones necessary for the wifi to work, my McAfee scanner to automatically start, etc. Even the appearance had changed because services allowing the standard vista theme had been disabled. I tried to just turn UAC and the Security Center back on, to reverse the change -- after the reboot, all the services remained disabled but now I got the annoying UAC nag every time I tried to do something as well.
