Run CMD as admin and copy/paste:

Code:

reg delete "HKLM\Software\Policies\Microsoft\Windows Defender" /f

I don't need to Delete Windows Defender. I just need to Know why I got Message in 1st Pic because I Already in Admin

Try to open it manually: Run as administrator
C:\Program Files\Windows Defender\MSASCuiL.exe

Try to reset Defender now in Services. Open Services in Admin mode and scroll down to Security Center
Right-click the Security Center service, and select restart.
Restart your computer.

If you still have the same issue, then try this in cmd:
1.Run the SFC scan

Code:

sfc /scannow

2.

Code:

DISM.exe /Online /Cleanup-image /Restorehealth

Lastly, check if date and time are OK.

Same is happening to me even after a clean install of Windows, I hope it gets fixed soon.

How do you get definition updates? WU?

Manually, if not working:
Antimalware updates change log - Windows Defender Security Intelligence

From cmd admin:

1.

Code:

cd %ProgramFiles%\Windows Defender

2. Shows definition that you have

Code:

MpCmdRun.exe -removedefinitions -dynamicsignatures

3. Will generate an error if not working

Code:

MpCmdRun.exe -SignatureUpdate
