User Account Control (UAC) is a mandatory access control enforcement feature introduced with Microsoft's Windows Vista [1] and Windows Server 2008 operating systems, with a more relaxed [2] 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.
User Account Control is a new infrastructure that requires user consent before allowing any action that requires administrative privileges. With this feature, all users, including users with administrative privileges, run in a standard user mode by default, since most applications do not require higher privileges.
When User Account Control is enabled, any process started with Administrator-level privileges does not inherit the drive mappings of the interactively logged on user, despite the same account being used. This can lead to scenarios where non-UAC processes such as Windows Explorer have access to an application on a network drive, but insufficient ...

Windows Vista aims to simplify power management by presenting concise names for power schemes and by reducing the number of default schemes to the following three schemes: Balanced, which is enabled by default and adjusts performance and power consumption based on user interaction; Power Saver, which reduces performance by favoring energy ...
Although User Account Control (UAC) is an important part of Vista's security infrastructure as it blocks software from silently gaining administrator privileges without the user's knowledge, it has been widely criticized for generating too many prompts. [197]
User Account Control uses a combination of heuristic scanning and "application manifests" to determine if an application requires administrator privileges. [19] Manifest ( .manifest ) files, first introduced with Windows XP, are XML files with the same name as the application and a suffix of ".manifest", e.g. Notepad.exe.manifest .
Windows Vista contains a range of new technologies and features that are intended to help network administrators and power users better manage their systems. Notable changes include a complete replacement of both the Windows Setup and the Windows startup processes, completely rewritten deployment mechanisms, new diagnostic and health monitoring tools such as random access memory diagnostic ...
