When an app attempts to run with an administrator's full access token, Windows first analyzes the executable file to determine its publisher. The UAC elevation prompts are color-coded to be app-specific, enabling for easier identification of an application's potential security risk. The consent prompt is presented when a user attempts to perform a task that requires a user's administrative access token. Administrators can also be required to provide their credentials by setting the User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode policy setting value to Prompt for credentials. The credential prompt is presented when a standard user attempts to perform a task that requires a user's administrative access token. The default, built-in UAC elevation component for an administrator account in Admin Approval Mode is called the consent prompt.

With the built-in UAC elevation component, members of the local Administrators group can easily perform an administrative task by providing approval. The alternative to running as a standard user is to run as an administrator in Admin Approval Mode. The default, built-in UAC elevation component for standard users is the credential prompt. With the built-in UAC elevation component, standard users can easily perform an administrative task by entering valid credentials for a local administrator account. Running as a standard user helps to maximize security for a managed environment. The recommended and more secure method of running Windows, is to ensure your primary user account is a standard user. When UAC is enabled, the user experience for standard users is different from administrator users. This prompt is called an elevation prompt, and its behavior can be configured via policy or registry. When the administrator needs to perform a task that requires the administrator access token, Windows automatically prompts the user for approval. As a result, all apps run as a standard user unless a user provides consent or credentials to approve an app to use a full administrative access tokenĪ user that is a member of the Administrators group can sign in, browse the Web, and read e-mail while using a standard user access token. Explorer.exe is the parent process from which all other user-initiated processes inherit their access token.

It's used to display the desktop by executing the process explorer.exe.

It's used to start applications that don't perform administrative tasks (standard user apps).

Contains the same user-specific information as the administrator access token, but the administrative Windows privileges and SIDs are removed.

When an administrator logs on, two separate access tokens are created for the user: a standard user access token and an administrator access token. The access token contains information about the level of access that the user is granted, including specific security identifiers (SIDs) and Windows privileges. When a user signs in, the system creates an access token for that user. The following diagram shows how the sign in process for an administrator differs from the sign in process for a standard user.īy default, both standard and administrator users access resources and execute apps in the security context of a standard user. To better understand how this process works, let's take a closer look at the Windows sign in process. When a standard user attempts to run an app that requires an administrator access token, UAC requires that the user provides valid administrator credentials.

A low integrity application is one that performs tasks that could potentially compromise the operating system, like as a Web browsĪpplications with lower integrity levels can't modify data in applications with higher integrity levels.

A high integrity application is one that performs tasks that modify system data, such as a disk partitioning application.

Integrity levels are measurements of trust: Windows protects processes by marking their integrity levels. Both the parent and child processes, however, must have the same integrity level. Child processes inherit the user's access token from the parent process. The only exception is the relationship that exists between parent and child processes. With UAC, each application that requires the administrator access token must prompt the end user for consent. This article describes how UAC works and how it interacts with the end-users.

UAC reduces the risk of malware by limiting the ability of malicious code to execute with administrator privileges. User Account Control (UAC) is a key part of Windows security.
