User Account Control Group Policy and registry key settings They can be configured locally by using the Local Security Policy snap-in (secpol.msc) or configured for the domain, OU, or specific groups by Group Policy. You can use security policies to configure how User Account Control works in your organization. User Account Control security policy settings UAC helps mitigate the impact of malware. User Account Control (UAC) is a fundamental component of Microsoft's overall security vision. Lastly, it can be used to enforce a higher level of compliance where administrators must actively consent or provide credentials for each administrative process. It also helps protect from inadvertent system-wide changes. Practical applicationsĪdmin Approval Mode in UAC helps prevent malware from silently installing without an administrator's knowledge.
Users continue to operate in the standard user security context, while enabling certain apps to run with elevated privileges, if needed. When an app needs to run with more than standard user rights, UAC allows users to run apps with their administrator token (with administrative groups and privileges) instead of their default, standard user access token. Additionally, actions such as installing new software and making configuration changes to the Windows Firewall, require more permissions than what is available to a standard user account. These types of apps are referred to as legacy apps. Other apps, especially those that were not specifically designed with security settings in mind, often require additional permissions to run successfully. Many apps, including those that are included with the operating system itself, are designed to work properly in this way. Additionally, any apps that are started using Windows Explorer (for example, by double-clicking a shortcut) also run with the standard set of user permissions. For instance, Windows Explorer automatically inherits standard user level permissions. Processes launched using a standard user token may perform tasks using access rights granted to a standard user. UAC allows all users to log on to their computers using a standard user account. UAC can block the automatic installation of unauthorized apps and prevent inadvertent changes to system settings.
With UAC, apps and tasks always run in the security context of a non-administrator account, unless an administrator specifically authorizes administrator-level access to the system.
