Resolution
The registry keys under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions] are the Group Policy Preference Client Side Extensions. The CSE name of the GUID {4D2F9B6F-1E52-4711-A382-6A8B1A003DE6} is RemoteApp and Desktop Connections. Please follow the steps below to resolve the issue.
1. Locate the registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\4D2F9B6F-1E52-4711-A382-6A8B1A003DE6}]
2. Take the ownership of this key: Right click on the registry key and choose Permissions option and click the Advanced button on the dialogue window.
