Dear Team,

I'm experiencing an issue while trying to enable the Defender feature on my server. Before, we had another antivirus (Cylance) installed, so we disabled the feature.
I tried a restorehealth, a restorehealth pointing to a wim created from a server that was from the same build, still experiencing the issue.

SFC Scannow :
Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection did not find any integrity violations

DISM restorehealth:
[===========================98.5%========================= ]
Error: 0xd0000034
DISM failed. No operation was performed.
For more information, review the log file.

DISM to enable Defender :
Error: 0x800f0831
DISM failed. No operation was performed.
For more information, review the log file.


Please find the required files attached to thread.
Many thanks in advance.

Hi Maxstar,

Many thanks for your answer.
Following the application of the fix, the DISM /online /cleanup-image /RestoreHealth Worked !
But sadly, I had an error while enabling the feature for Defender.
Please find the info in the attached objects.

Best Regards,

Great, please try to install the Windows Defender feature again and post the result. If it fails attach a new copy of the CBS logs.
