Target a Specific User with Security Filtering

  1. Grant the user (or a security group) Read and Apply Group Policy on the GPO.
  2. Optional: Remove Authenticated Users from Security Filtering if you want exclusive targeting.
  3. Be cautious—ensure the correct principals retain required rights.
