Introduced in Windows Vista, User Account Control (UAC) offers an approach to encourage "super-user when necessary".
Windows 9x: all applications enjoyed system-wide privileges rivaling those of the operating system itself.MS-DOS and Windows versions 1.0 to 3.11: all applications had privileges equivalent to the operating system.Microsoft does not certify applications as Windows-compliant if they require administrator privileges such applications may not use the Windows-compliant logo with their packaging. Subsequent versions of Windows and Microsoft applications encouraged the use of non-administrator user-logons, yet some applications continued to require administrator rights. This had an obvious security component, but also an administrative component, in that it prevented users from accidentally changing system settings.Įarly Microsoft home operating-systems (such as MS-DOS, Windows 95- 98 and Windows Me) did not have a concept of different user-accounts on the same machine. Operating systems on mainframes and on servers have differentiated between superusers and userland for decades. One prominent use of this is Internet Explorer 7's "Protected Mode". To reduce the possibility of lower-privilege applications communicating with higher-privilege ones, another new technology, User Interface Privilege Isolation, is used in conjunction with User Account Control to isolate these processes from each other.
UAC uses Mandatory Integrity Control to isolate running processes with different privileges. In other words, a user account may have administrator privileges assigned to it, but applications that the user runs do not inherit those privileges unless they are approved beforehand or the user explicitly authorises it. In this way, only applications trusted by the user may receive administrative privileges and malware are kept from compromising the operating system.

It aims to improve the security of Microsoft Windows by limiting application software to standard user privileges until an administrator authorises an increase or elevation. User Account Control ( UAC) is a mandatory access control enforcement feature introduced with Microsoft's Windows Vista and Windows Server 2008 operating systems, with a more relaxed version also present in Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows 10, and Windows 11.
