2.3.17.6 Ensure 'User Account Control: Run all administrators in Admin Approval Mode' is set to 'Enabled'

Information

This policy setting controls the behavior of all User Account Control (UAC) policy settings for the computer. If you change this policy setting, you must restart your computer.

The recommended state for this setting is: Enabled.

Note: If this policy setting is disabled, the Security Center notifies you that the overall security of the operating system has been reduced.

Rationale:

This is the setting that turns on or off UAC. If this setting is disabled, UAC will not be used and any security benefits and risk mitigations that are dependent on UAC will not be present on the system.

Impact:

None - this is the default behavior. Users and administrators will need to learn to work with UAC prompts and adjust their work habits to use least privilege operations.

Warning: Windows Autopilot - Policy Conflicts: This policy requires a reboot to apply. As a result, prompts may appear when modifying user account control (UAC) settings during the Out of the Box Experience (OOBE) using the device Enrollment Status Page (ESP). Increased prompts are more likely if the device reboots after policies are applied. To work around this issue, the policies can be targeted to users instead of devices so that they apply later in the process. An exception to this recommendation may be needed if Windows AutoPilot is used.

Solution

To establish the recommended configuration, set the following Device Configuration Policy to Enabled:

To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Endpoint protection)

Click Create

Enter a Name

Click Next

Configure the following Setting

Path: Endpoint protection/Local device security options/User account control
Setting Name: Run all admins in Admin Approval Mode
Configuration: Enabled

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.

Note #2: This setting can also be created via a Custom Configuration Profile using the following OMA-URI:

Name: <Enter name>
Description: <Enter Description>
OMA-URI: ./Device/Vendor/MSFT/Policy/Config/LocalPoliciesSecurityOptions/UserAccountControl_RunAllAdministratorsInAdminApprovalMode
Data type: Integer
Value: 1

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Default Value:

Enabled. (Admin Approval Mode is enabled. This policy must be enabled and related UAC policy settings must also be set appropriately to allow the built-in Administrator account and all other users who are members of the Administrators group to run in Admin Approval Mode.)
