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 uses a combination of heuristic scanning and "application manifests" to determine if an application requires administrator privileges. [19] 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. When an application is ...
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 ...
Finally, the concept of "Run as administrator" isn't and won't only be unique to Vista, while User Account Control most certainly is. Run as administrator ought to be separate so it can cover the same concept as it relates to multiple operating systems. Reswobslc 18:11, 10 March 2007 (UTC)
User Account Control, or UAC is perhaps the most significant and visible of these changes. UAC is a security technology that makes it possible for users to use their computer with fewer privileges by default, to stop malware from making unauthorized changes to the system. This was often difficult in previous versions of Windows, as the previous ...
Mandatory Integrity Control is defined using a new access control entry (ACE) type to represent the object's IL in its security descriptor.In Windows, Access Control Lists (ACLs) are used to grant access rights (read, write, and execute permissions) and privileges to users or groups.
By default, Windows Vista and later use User Account Control (UAC) to enforce security. One of UAC's features denies administrative rights to a user who accesses network shares on the local computer over a network, unless the accessing user is registered on a Windows domain or using the built in Administrator account.
This poses security risks as local users would be able to access the computer via the built-in administrator account if the password is left blank, so the account is disabled by default in Windows Vista and later systems due to the introduction of User Account Control (UAC). [13] Remote users are unable to access the built-in administrator account.
