Hello Charles_MH,
Thank you for posting in Microsoft Community forum.
It sounds like you're experiencing an issue with BitLocker and group policies on Windows 11. Here are a few steps you can take to troubleshoot and resolve this issue:
- Verify BitLocker Group Policy Settings:
Ensure that the BitLocker policy settings are correctly configured for Windows 11 Pro.
You can try to put one Win 11 Pro to the same OU as Win 10 Pro.
- Check group policy result.
For checking Computer Configuration within gpresult, we can follow steps below.
Logon this machine using administrator account.
Open CMD (run as Administrator).
Type gpresult /h C:\gpo.html and click Enter.
Open gpo.html and check gpo setting under "Computer Details".
3.Please check if the problem occurs on only one Win 11 Pro or all the Win 11 pro。
- Review Event Logs:
Check the Event Viewer logs on the Windows 11 machines for any BitLocker-related errors or warnings. This can often provide more specific information about what might be going wrong.
- Ensure Windows 11 Pro Compliance:
Ensure your Windows 11 devices meet all of the necessary prerequisites and system requirements for BitLocker to function correctly.
- Testing on a New Policy:
Create a new GPO specifically tailored for one Windows 11 and test if applying this resolves the issue as a temporary measure. This helps in isolating whether the issue is with the existing GPO configurations.
