found UAC bug in Vista
Posted by admin on Jun 28th, 2007
i have found a bug in Vista related with UAC setting.there are two ways to turn on UAC setting: 1. from user accounts in Control Panel 2. from windows security centerthe first one works well and asks for system restart. the second one does not.i used the second one recently and then i logged in as plain user. UAC setting was not changed and did not work. i had to solve the problem by using the first way: control panel.

MarcoAre you using the builtin System Administrator when you turn UAC on from the Security Center?I did some testing and here's what I found.If UAC is turned OFF and you turn it back ON from within Security Center, and you are logged on with the Builtin System Administrator account, you will not be prompted for a restart although UAC WILL be turned ON for all user accounts.I believe this behavior is due to the fact that the "Elevate for administrator privilege" is turned off, by default on this account in the Security Policy for the machine.If you are logged on with any other administrator or standard user account and turn UAC ON from the Security Center, you will be prompted to reboot as expected.If you are logged on with the Builtin System Administrator account and turn the UAC OFF, you will still be prompted to reboot.When using the Builtin System Administrator account, you may see some unexpected behavior since this account uses a completely different set of permissions than all the other account types.
