Computer Tip: Difference between User Access Control in Windows 7 & 8

User Access Control (UAC) is a security technology that first came with Windows Vista and evolved with subsequent Windows versions. It will help limit normal privileges available for local administrators as well as others with elevated levels. Over the recent versions, UAC has been tweaked to include less requests for access.

In windows 7, if set to never notify, UAC is actually disabled. With Windows 8, the Never notify setting does not disable the UAC but instead removes any prompts the user may receive. So when an application that is UAC aware makes a request for privilege elevation it will just happen automatically.

UAC is required for WinRT-based applications (such as Windows Store and modern apps) to execute. The application still has to request the elevation but will be approved.

An application in windows 8 that just assumes it has administrator privileges and doesn’t ask for elevation, it will ultimately fail.

To actually disable UAC in windows 8 you would have to modify the EnableLUA value in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and set the value of 0. A reboot is but this will block the modern applications and is not a supported state of the OS.
