Software restriction policy in AD with incompatibility in Windows 11

Hi You can try this troubleshooting steps and see if it is working

When an Active Directory (AD) software blocking policy works on Windows 10 but not on Windows 11, there are several potential causes and troubleshooting steps to consider. Here's a structured approach to diagnose and resolve the issue:

Step-by-Step Troubleshooting
Check Group Policy Update Status:

On the Windows 11 machine, ensure that the Group Policy has been updated. Run the following command in Command Prompt:
gpupdate /force

Restart the computer after running this command to ensure that all policies are applied correctly.

Verify Group Policy Application:
On the Windows 11 machine, run the Resultant Set of Policy (RSoP) or Group Policy Results tool:
rsop.msc
or
gpresult /h gpresult.html
Review the report to check if the software blocking policy is listed and applied as expected.

Check Event Viewer:

Look for Group Policy related events in the Event Viewer on the Windows 11 machine. Navigate to:
rust
Event Viewer -> Windows Logs -> System
Look for any errors or warnings related to Group Policy application.

Review Policy Configuration:

Confirm that the software blocking policy is correctly configured and linked to the appropriate Organizational Unit (OU) in Active Directory.
Ensure there are no conflicting policies that might override the software blocking policy.

Compatibility Issues:

Windows 11 might have different security baselines or settings compared to Windows 10. Ensure that the software blocking policy is compatible with Windows 11.
Review Microsoft’s documentation for any known issues or differences in Group Policy behavior between Windows 10 and Windows 11.

Test Policy in Isolation:

Create a test OU and apply only the software blocking policy to this OU. Move the Windows 11 machine to this OU and see if the policy applies correctly.
This helps to rule out any interference from other policies.

Policy Scope and Security Filtering:

Verify that the policy is correctly scoped to include the Windows 11 machine and the user accounts.
Check security filtering and ensure the Authenticated Users group has the Read and Apply Group Policy permissions.

Check AD Replication:

Ensure that Active Directory replication is functioning correctly, and all domain controllers have the updated policy. Run the following command on the domain controller:
repadmin /replsummary

Windows 11 Specific Settings:
Windows 11 might require additional configurations or updates for certain policies. Check for any specific updates or hotfixes for Windows 11 that address Group Policy issues.

Additional Checks
Permissions: Ensure that the Windows 11 machine has the correct permissions to read and apply the Group Policy.
Policy Precedence: Make sure that the software blocking policy has higher precedence than any other policies that might allow the software.
Logs: Check for detailed logs in the C:\Windows\System32\GroupPolicy\ directory, especially the gpt.ini file, which might provide insights into why the policy is not applying.
Conclusion
By following these steps, you should be able to identify and resolve the issue causing the software blocking policy to not apply correctly on Windows 11. If the problem persists, consider consulting Microsoft's support or forums for any additional guidance specific to Windows 11 and Active Directory Group Policies.
