User Account Control: Switch to the secure desktop when prompting for elevation

Applies to

  • Windows 11
  • Windows 10

Describes the best practices, location, values, policy management and security considerations for the User Account Control: Switch to the secure desktop when prompting for elevation security policy setting.

Reference

This policy setting determines whether the elevation request prompts on the interactive user desktop or on the secure desktop.

The secure desktop presents the sign-in UI and restricts functionality and access to the system until the sign-in requirements are satisfied.

The secure desktop’s primary difference from the user desktop is that only trusted processes running as SYSTEM are allowed to run here (that is, nothing is running at the user’s privilege level). The path to get to the secure desktop from the user desktop must also be trusted through the entire chain.

Possible values

  • Enabled

    All elevation requests by default go to the secure desktop.

  • Disabled

    All elevation requests go to the interactive user desktop.

Best practices

  • Enable the User Account Control: Switch to the secure desktop when prompting for elevation setting. The secure desktop helps protect against input and output spoofing by presenting the credentials dialog box in a protected section of memory that is accessible only by trusted system processes.

Policy management

This section describes features and tools that are available to help you manage this policy.

Restart requirement

None. Changes to this policy become effective without a device restart when they're saved locally or distributed through Group Policy.

Group Policy

All auditing capabilities are integrated in Group Policy. You can configure, deploy, and manage these settings in the Group Policy Management Console (GPMC) or Local Security Policy snap-in for a domain, site, or organizational unit (OU).

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Vulnerability

Elevation prompt dialog boxes can be spoofed, causing users to disclose their passwords to malicious software. Mouse cursors can be spoofed by hiding the real cursor and replacing it with an offset so the cursor is actually pointing to the Allow button.

Countermeasure

Enable the User Account Control: Switch to the secure desktop when prompting for elevation setting. The secure desktop helps protect against input and output spoofing by presenting the credentials dialog box in a protected section of memory that is accessible only by trusted system processes.

Potential impact

None. This non-impact state is the default configuration.
