AppLocker blocks administrators and other high privileged group’s users from executing files on a Windows 7 SP1-based or Windows Server 2008 R2 SP1-based computer

Symptoms


Consider the following scenario:
  • You deploy an AppLocker policy together with a default rule on a Windows 7 Service Pack 1 (SP1)-based or Windows Server 2008 R2 SP1-based computer.
  • The administrative users or other high privileged group’s users can run executable files that are in a whitelist that is defined in AppLocker policy without receiving a User Account Control (UAC) prompt on the computer.
  • You create a user named "AdminUser" as a member of the Administrators group or other high privileged group.
  • You use "AdminUser" to run an executable file that is in the whitelist.
In this scenario, you still have to use the Run as Administrator option to run the file. Otherwise, the operation fails, and you receive the following error message:
Your system administrator has blocked this program.

Cause

This issue occurs because the Administrators security identifier in the user's access token is disabled by UAC.
