User Account Control

</header>

User Account Control (UAC) is a <a href="Mandatory_access_control" title="Mandatory access control">mandatory access control</a> enforcement feature introduced with <a href="Microsoft" title="Microsoft">Microsoft</a>'s <a href="Windows_Vista" title="Windows Vista">Windows Vista</a><a href="#cite_note-1">[1]</a> and <a href="Windows_Server_2008" title="Windows Server 2008">Windows Server 2008</a> <a href="Operating_system" title="Operating system">operating systems</a>, with a more relaxed<a href="#cite_note-winsupersiteuac-2">[2]</a> version also present in the versions after Vista, being <a href="Windows_7" title="Windows 7">Windows 7</a>, <a href="Windows_Server_2008_R2" title="Windows Server 2008 R2">Windows Server 2008 R2</a>, <a href="Windows_8" title="Windows 8">Windows 8</a>, <a href="Windows_Server_2012" title="Windows Server 2012">Windows Server 2012</a>, <a href="Windows_8.1" title="Windows 8.1">Windows 8.1</a>, <a href="Windows_Server_2012_R2" title="Windows Server 2012 R2">Windows Server 2012 R2</a>, <a href="Windows_10" title="Windows 10">Windows 10</a>, and <a href="Windows_11" title="Windows 11">Windows 11</a>. It aims to improve the security of <a href="Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> by limiting <a href="Application_software" title="Application software">application software</a> to standard <a href="User_privilege" class="mw-redirect" title="User privilege">user privileges</a> until an <a href="System_administrator" title="System administrator">administrator</a> authorises an increase or elevation. In this way, only applications trusted by the user may receive administrative privileges and <a href="Malware" title="Malware">malware</a> are kept from compromising the operating system. 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.

UAC uses <a href="Mandatory_Integrity_Control" title="Mandatory Integrity Control">Mandatory Integrity Control</a> to isolate running processes with different privileges. To reduce the possibility of lower-privilege applications communicating with higher-privilege ones, another new technology, <a href="User_Interface_Privilege_Isolation" title="User Interface Privilege Isolation">User Interface Privilege Isolation</a>, is used in conjunction with User Account Control to isolate these processes from each other.<a href="#cite_note-3">[3]</a> One prominent use of this is <a href="Internet_Explorer_7" title="Internet Explorer 7">Internet Explorer 7</a>'s "Protected Mode".<a href="#cite_note-4">[4]</a>

Operating systems on mainframes and on servers have differentiated between <a href="Superusers" class="mw-redirect" title="Superusers">superusers</a> and <a href="Userland_(computing)" class="mw-redirect" title="Userland (computing)">userland</a> for decades. This had an obvious security component, but also an administrative component, in that it prevented users from accidentally changing system settings.

Early Microsoft <a href="Home_computer" title="Home computer">home operating-systems</a> (such as <a href="MS-DOS" title="MS-DOS">MS-DOS</a> and <a href="Windows_9x" title="Windows 9x">Windows 9x</a>) did not have a concept of different user-accounts on the same machine. Subsequent versions of Windows and Microsoft applications encouraged the use of non-administrator user-logons, yet some applications continued to require administrator rights. 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.

<div class="mw-heading mw-heading2"><h2 id="Behavior_in_Windows_versions">Behavior in Windows versions</h2></div>

<ul><li><a href="Windows_1.0x" class="mw-redirect" title="Windows 1.0x">Windows 1.0</a>–<a href="Windows_3.11" class="mw-redirect" title="Windows 3.11">3.11</a> and <a href="Windows_9x" title="Windows 9x">Windows 9x</a>: all applications had privileges equivalent to the operating system;</li>

<li>All versions of <a href="Windows_NT" title="Windows NT">Windows NT</a> up to, and including, <a href="Windows_XP" title="Windows XP">Windows XP</a> and <a href="Windows_Server_2003" title="Windows Server 2003">Windows Server 2003</a>: introduced multiple user-accounts, but in practice most users continued to function as an administrator for their normal operations. Further, some applications would require that the user be an administrator for some or all of their functions to work.<a href="#cite_note-Channel_9-5">[5]</a></li>

<li><a href="Windows_Vista" title="Windows Vista">Windows Vista</a> and <a href="Windows_Server_2008" title="Windows Server 2008">Windows Server 2008</a>: Microsoft developed Vista security firstly from the Limited User Account (LUA), then renamed the concept to User Account Protection (UAP) before finally shipping User Account Control (UAC).<a href="#cite_note-6">[6]</a> Introduced in <a href="Windows_Vista" title="Windows Vista">Windows Vista</a>, User Account Control (UAC) offers an approach to encourage "super-user when necessary". The key to UAC lies in its ability to elevate privileges without changing the user context (user "Bob" is still user "Bob"). As always, it is difficult to introduce new security features without breaking compatibility with existing applications.

<ul><li>When someone logs into Vista as a standard user, the system sets up a logon session and assigns a <a href="Token_(Windows_NT_architecture)" class="mw-redirect" title="Token (Windows NT architecture)">token</a> containing only the most basic privileges. In this way, the new logon session cannot make changes that would affect the entire system.</li>

<li>When a person logs in as a user with membership in the Administrators group, the system assigns two separate tokens: the first token contains all privileges typically awarded to an administrator, and the second is a restricted token similar to what a standard user would receive.

<ul><li>User applications, including the <a href="Windows_Shell" class="mw-redirect" title="Windows Shell">Windows Shell</a>, then start with the restricted token, resulting in a reduced-privilege environment – even when running under an Administrator account.</li>

<li>When an application requests higher privileges or when a user selects a "Run as administrator" option, UAC will prompt standard users to enter the credentials of an Administrator account and prompt Administrators for confirmation and, if consent is given, continue or start the process using an unrestricted token.<a href="#cite_note-kennykerr-7">[7]</a></li></ul></li></ul></li>

<li><a href="Windows_7" title="Windows 7">Windows 7</a> and <a href="Windows_Server_2008_R2" title="Windows Server 2008 R2">Windows Server 2008 R2</a>: Microsoft included a user interface to change User Account Control settings, and introduced one new notification mode: the default setting. By default, UAC does not prompt for consent when users make changes to Windows settings that require elevated permission through programs stored in <a href="%25SystemRoot%25" class="mw-redirect" title="%SystemRoot%">%SystemRoot%</a> and digitally signed by Microsoft. Programs that require permission to run still trigger a prompt. Other User Account Control settings that can be changed through the new UI could have been accessed through the <a href="Windows_Registry" title="Windows Registry">registry</a> in Windows Vista.<a href="#cite_note-8">[8]</a></li>

<li><a href="Windows_8" title="Windows 8">Windows 8</a>/<a href="Windows_8.1" title="Windows 8.1">8.1</a> and <a href="Windows_Server_2012" title="Windows Server 2012">Windows Server 2012</a>/<a href="Windows_Server_2012_R2" title="Windows Server 2012 R2">R2</a>: add a design change. When UAC is triggered, all applications and the taskbar are hidden when the desktop is dimmed.</li>

<li><a href="Windows_10" title="Windows 10">Windows 10</a> and <a href="Windows_Server_2016" title="Windows Server 2016">Windows Server 2016</a>-<a href="Windows_Server_2022" title="Windows Server 2022">2022</a>: early versions have the same layout as <a href="Windows_8" title="Windows 8">Windows 8</a> and <a href="Windows_8.1" title="Windows 8.1">8.1</a>. The <a href="Anniversary_Update" class="mw-redirect" title="Anniversary Update">Anniversary Update</a> (including Windows Server 2016, which is based on said update) adds a more modern look, along with support for dark mode. Also, Windows 10 adds support for <a href="Windows_Hello" class="mw-redirect" title="Windows Hello">Windows Hello</a> in the User Account Control dialog box.</li>

<li><a href="Windows_11" title="Windows 11">Windows 11</a> and <a href="Windows_Server_2025" title="Windows Server 2025">Windows Server 2025</a>: has mostly the same layout as in later versions of <a href="Windows_10" title="Windows 10">Windows 10</a>, but with visual changes that match the rest of the operating system's new look and feel.</li></ul>

<div class="mw-heading mw-heading2"><h2 id="Tasks_that_trigger_a_UAC_prompt">Tasks that trigger a UAC prompt</h2></div>

Tasks that require administrator privileges will trigger a UAC prompt (if UAC is enabled); they are typically marked by a security shield icon with the 4 colors of the Windows logo (in Vista and Windows Server 2008) or with two panels yellow and two blue (Windows 7, Windows Server 2008 R2 and later). In the case of executable files, the icon will have a security shield overlay. The following tasks require administrator privileges:<a href="#cite_note-9">[9]</a><a href="#cite_note-10">[10]</a>

<ul><li>Running an Application as an Administrator</li>

<li>Changes to system-wide settings</li>

<ul><li>The <a href="%25USERPROFILE%25" class="mw-redirect" title="%USERPROFILE%">%USERPROFILE%</a> (e.g. C:\Users\{logged in user}) folder and its sub-folders.

<ul><li>Most of the time this is in %APPDATA%. (e.g. C:\Users\{logged in user}\AppData), by default, this is a <a href="Hidden_file_and_hidden_directory#DOS_and_MS_Windows" title="Hidden file and hidden directory">hidden folder.</a>

<ul><li><a href="Google_Chrome" title="Google Chrome">Chrome</a>'s and <a href="Firefox" title="Firefox">Firefox</a>'s installer ask for admin rights during install, if given, Chrome will install in the Program Files folder and be usable for all users, if denied, Chrome will install in the %APPDATA% folder instead and only be usable by the current user.</li></ul></li></ul></li>

Common tasks, such as changing the time zone, do not require administrator privileges<a href="#cite_note-11">[11]</a> (although changing the system time itself does, since the system time is commonly used in security protocols such as <a href="Kerberos_(protocol)" title="Kerberos (protocol)">Kerberos</a>). A number of tasks that required administrator privileges in earlier versions of Windows, such as installing critical Windows updates, no longer require administrator privileges in Vista.<a href="#cite_note-12">[12]</a> Any program can be run as administrator by right-clicking its icon and clicking "Run as administrator", except MSI or MSU packages as, due to their nature, if administrator rights will be required a prompt will usually be shown. Should this fail, the only workaround is to run a Command Prompt as an administrator and launch the MSI or MSP package from there.

<div class="mw-heading mw-heading2"><h2 id="Features">Features</h2></div>

User Account Control asks for credentials in a Secure Desktop mode, where the entire screen is temporarily dimmed, <a href="Windows_Aero" title="Windows Aero">Windows Aero</a> disabled, and only the authorization window at full brightness, to present only the elevation user interface (UI). Normal applications cannot interact with the Secure Desktop. This helps prevent spoofing, such as overlaying different text or graphics on top of the elevation request, or tweaking the mouse pointer to click the confirmation button when that's not what the user intended.<a href="#cite_note-13">[13]</a> If an administrative activity comes from a minimized application, the secure desktop request will also be minimized so as to prevent the <a href="Focus_(computing)" title="Focus (computing)">focus</a> from being lost. It is possible to disable Secure Desktop, though this is inadvisable from a security perspective.<a href="#cite_note-bott,edd_(2007)-14">[14]</a>

In earlier versions of Windows, Applications written with the assumption that the user will be running with administrator privileges experienced problems when run from limited user accounts, often because they attempted to write to machine-wide or system directories (such as Program Files) or registry keys (notably <a href="HKEY_LOCAL_MACHINE" class="mw-redirect" title="HKEY LOCAL MACHINE">HKLM</a>).<a href="#cite_note-Channel_9-5">[5]</a> UAC attempts to alleviate this using File and Registry Virtualization, which redirects writes (and subsequent reads) to a per-user location within the user's profile. For example, if an application attempts to write to a directory such as "C:\Program Files\appname\settings.ini" to which the user does not have write permission, the write will be redirected to "C:\Users\username\AppData\Local\VirtualStore\Program Files\appname\settings.ini". The redirection feature is only provided for non-elevated 32-bit applications, and only if they do not include a manifest that requests specific privileges.<a href="#cite_note-15">[15]</a>

There are a number of configurable UAC settings. It is possible to:<a href="#cite_note-16">[16]</a>

<ul><li>Require administrators to re-enter their password for heightened security,</li>

<li>Require the user to press <a href="Control-Alt-Delete" title="Control-Alt-Delete">Ctrl+Alt+Del</a> as part of the authentication process for heightened security;</li>

<li>Disable only file and registry virtualization<a href="#cite_note-17">[17]</a></li>

<li>Disable Admin Approval Mode (UAC prompts for administrators) entirely; note that, while this disables the UAC confirmation dialogs, it does not disable Windows' built-in <a href="Principle_of_least_privilege" title="Principle of least privilege">LUA</a> feature, which means that users, even those marked as administrators, are still limited users with no true administrative access.</li></ul>

<a href="Command_Prompt_(Windows)" class="mw-redirect" title="Command Prompt (Windows)">Command Prompt</a> windows that are running elevated will prefix the title of the window with the word "Administrator", so that a user can discern which instances are running with elevated privileges.<a href="#cite_note-18">[18]</a>

A distinction is made between elevation requests from a signed executable and an unsigned executable; and if the former, whether the publisher is 'Windows Vista'. The color, icon, and wording of the prompts are different in each case; for example, attempting to convey a greater sense of warning if the executable is unsigned than if not.<a href="#cite_note-19">[19]</a>

<a href="Internet_Explorer_7" title="Internet Explorer 7">Internet Explorer 7</a>'s "Protected Mode" feature uses UAC to run with a 'low' <a href="Mandatory_Integrity_Control" title="Mandatory Integrity Control">integrity level</a> (a Standard user token has an integrity level of 'medium'; an elevated (Administrator) token has an integrity level of 'high'). As such, it effectively runs in a sandbox, unable to write to most of the system (apart from the Temporary Internet Files folder) without elevating via UAC.<a href="#cite_note-kennykerr-7">[7]</a><a href="#cite_note-MRtechnet-20">[20]</a> Since toolbars and ActiveX controls run within the Internet Explorer process, they will run with low privileges as well, and will be severely limited in what damage they can do to the system.<a href="#cite_note-21">[21]</a>

<div class="mw-heading mw-heading2"><h2 id="Requesting_elevation">Requesting elevation</h2></div>

A program can request elevation in a number of different ways. One way for program developers is to add a requestedPrivileges section to an XML document, known as the <a href="Manifest_(CLI)" title="Manifest (CLI)">manifest</a>, that is then embedded into the application. A manifest can specify dependencies, visual styles, and now the appropriate security context:

</requestedPrivileges>

</security>

</trustInfo>

</assembly>

</pre></div>

Setting the level attribute for requestedExecutionLevel to "asInvoker" will make the application run with the token that started it, "highestAvailable" will present a UAC prompt for administrators and run with the usual reduced privileges for standard users, and "requireAdministrator" will require elevation.<a href="#cite_note-22">[22]</a> In both highestAvailable and requireAdministrator modes, failure to provide confirmation results in the program not being launched.

An executable that is marked as "<code>requireAdministrator</code>" in its manifest cannot be started from a non-elevated process using <code>CreateProcess()</code>. Instead, <code>ERROR_ELEVATION_REQUIRED</code> will be returned. <code>ShellExecute()</code> or <code>ShellExecuteEx()</code> must be used instead. If an <code>HWND</code> is not supplied, then the dialog will show up as a blinking item in the taskbar.

Inspecting an executable's manifest to determine if it requires elevation is not recommended, as elevation may be required for other reasons (setup executables, application compatibility). However, it is possible to programmatically detect if an executable will require elevation by using <code>CreateProcess()</code> and setting the <code>dwCreationFlags</code> parameter to <code>CREATE_SUSPENDED</code>. If elevation is required, then <code>ERROR_ELEVATION_REQUIRED</code> will be returned.<a href="#cite_note-23">[23]</a> If elevation is not required, a success return code will be returned at which point one can use <code>TerminateProcess()</code> on the newly created, suspended process. This will not allow one to detect that an executable requires elevation if one is already executing in an elevated process, however.

A new process with elevated privileges can be spawned from within a .NET application using the "<code>runas</code>" verb. An example using <a href="C_Sharp_(programming_language)" title="C Sharp (programming language)">C#</a>:

<div class="mw-highlight mw-highlight-lang-csharp mw-content-ltr" dir="ltr"><pre>System.Diagnostics.Process proc = new System.Diagnostics.Process();

proc.StartInfo.FileName = "C:\\Windows\\system32\\notepad.exe";

proc.StartInfo.Verb = "runas"; // Elevate the application

proc.StartInfo.UseShellExecute = true;

proc.Start();

</pre></div>

In a native <a href="Win32" class="mw-redirect" title="Win32">Win32</a> application the same "<code>runas</code>" verb can be added to a <code>ShellExecute()</code> or <code>ShellExecuteEx()</code> call:<a href="#cite_note-kennykerr-7">[7]</a>

<div class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><pre>ShellExecute(hwnd, "runas", "C:\\Windows\\Notepad.exe", 0, 0, SW_SHOWNORMAL);

</pre></div>

In the absence of a specific directive stating what privileges the application requests, UAC will apply <a href="Heuristic_algorithm" class="mw-redirect" title="Heuristic algorithm">heuristics</a>, to determine whether or not the application needs administrator privileges. For example, if UAC detects that the application is a setup program, from clues such as the filename, versioning fields, or the presence of certain sequences of bytes within the executable, in the absence of a manifest it will assume that the application needs administrator privileges.<a href="#cite_note-24">[24]</a>

<div class="mw-heading mw-heading2"><h2 id="Security">Security</h2></div>

UAC is a <a href="Convenience" title="Convenience">convenience</a> feature; it neither introduces a security boundary nor prevents execution of <a href="Malware" title="Malware">malware</a>.<a href="#cite_note-25">[25]</a><a href="#cite_note-26">[26]</a><a href="#cite_note-27">[27]</a><a href="#cite_note-28">[28]</a>

Leo Davidson discovered that Microsoft weakened UAC in <a href="Windows_7" title="Windows 7">Windows 7</a> through exemption of about 70 Windows programs from displaying a UAC prompt and presented a <a href="Proof_of_concept" title="Proof of concept">proof of concept</a> for a <a href="Privilege_escalation" title="Privilege escalation">privilege escalation</a>.<a href="#cite_note-29">[29]</a>

Stefan Kanthak presented a proof of concept for a privilege escalation via UAC's installer detection and <a href="IExpress" title="IExpress">IExpress</a> installers.<a href="#cite_note-30">[30]</a>

Stefan Kanthak presented another proof of concept for <a href="Arbitrary_code_execution" title="Arbitrary code execution">arbitrary code execution</a> as well as privilege escalation via UAC's auto-elevation and binary planting.<a href="#cite_note-31">[31]</a>

<div class="mw-heading mw-heading2"><h2 id="Criticism">Criticism</h2></div>

There have been complaints that UAC notifications slow down various tasks on the computer such as the initial installation of software onto <a href="Windows_Vista" title="Windows Vista">Windows Vista</a>.<a href="#cite_note-32">[32]</a> It is possible to turn off UAC while installing software, and re-enable it at a later time.<a href="#cite_note-33">[33]</a> However, this is not recommended since, as <a href="Windows_Registry#Virtualization" title="Windows Registry">File & Registry Virtualization</a> is only active when UAC is turned on, user settings and configuration files may be installed to a different place (a system directory rather than a user-specific directory) if UAC is switched off than they would be otherwise.<a href="#cite_note-bott,edd_(2007)-14">[14]</a> Also <a href="Internet_Explorer_7" title="Internet Explorer 7">Internet Explorer 7</a>'s "Protected Mode", whereby the browser runs in a sandbox with lower privileges than the standard user, relies on UAC; and will not function if UAC is disabled.<a href="#cite_note-MRtechnet-20">[20]</a>

<a href="Yankee_Group" title="Yankee Group">Yankee Group</a> analyst Andrew Jaquith said, six months before Vista was released, that "while the new security system shows promise, it is far too chatty and annoying."<a href="#cite_note-pcworlduac-34">[34]</a> By the time Windows Vista was released in November 2006, <a href="Microsoft" title="Microsoft">Microsoft</a> had drastically reduced the number of <a href="Operating_system" title="Operating system">operating system</a> tasks that triggered UAC prompts, and added file and registry virtualization to reduce the number of <a href="Legacy_system" title="Legacy system">legacy</a> applications that triggered UAC prompts.<a href="#cite_note-Channel_9-5">[5]</a> However, David Cross, a product unit manager at Microsoft, stated during the <a href="RSA_Conference" title="RSA Conference">RSA Conference</a> 2008 that UAC was in fact designed to "annoy users," and force independent software vendors to make their programs more secure so that UAC prompts would not be triggered.<a href="#cite_note-35">[35]</a> In response to these criticisms, Microsoft altered UAC activity in <a href="Windows_7" title="Windows 7">Windows 7</a>. For example, by default users are not prompted to confirm many actions initiated with the mouse and keyboard alone such as operating Control Panel applets.

In a controversial article, <a href="New_York_Times" class="mw-redirect" title="New York Times">New York Times</a> Gadgetwise writer Paul Boutin said "Turn off Vista's overly protective User Account Control. Those pop-ups are like having your mother hover over your shoulder while you work."<a href="#cite_note-36">[36]</a> Computerworld journalist Preston Gralla described the NYT article as "...one of the worst pieces of technical advice ever issued."<a href="#cite_note-37">[37]</a>
