The workstation is in a Protection Group and Agent Version 5.0.3.4708 is installed.
The workstation was added over the Active Directory and the AD shows Windows 10 Professional is installed. I also logged into the workstation and yes indeed Windows 10 Professional is installed. Windows 11 is blocked from installing in our Network using a GPO and the Workstation was not upgraded to Windows 11 and then reset back to Windows 10.
Its been showing the warning since Tuesday. Removing it from the Protection Group and re-adding it does not help.
