Windows 10: Windows defender crashing when i open windows security

Hi , i have a problem with windows defender, when i open windows defender ,crashing my windows defender how to fix that ?

:)

 

Windows Defender Security Centre crashes on opening

Every time I try to open Windows Defender Security Centre, the window opens and closes immediately. There is no error logged in the event logs.

The old Windows Defender interface - MSASCui.exe opens just fine; the problem lies with MSASCuiL.exe which crashes instantly after opening.

I do not have any other antivirus software installed, nor have I ever. Scans with Microsoft Safety Scanner and MSASCui.exe do not find any malware.

Steps tried

1. All the steps listed here on the troubleshooting article.

2. sfc /scannow reveals no problems

3. dism /online /cleanup-image /restorehealth completes successfully but to no avail

4. Clean boot performed

5. In-place install performed

6. Attempted to open in safe mode

None of the steps above seem to work.

I am using a desktop I built myself, running windows 10 v1703 build 15063.632. The Defender Security Centre has worked in the past but for some strange reason has not for the past week, or so I noticed.

Please do assist - a clean fresh install is however not an acceptable solution as this is a critical work computer.

 

"Attestation" A new feature coming to Windows Defender in Windows 10

Tech Republic - Upcoming Windows Defender feature will tell you when security fails

This seems very promising. Microsoft is in the unique position to know what Windows should look like, even before Windows Update pushes out new changes. As long as MS can properly sync WD with WU changes AND this new features does not make any "noticeable" hit on system performance/resources, all without any false positives, this should be a big step forward for consumer security, and a blow to the bad guys - always a good thing.

Of course, there will likely be some hiccups the Windows/Microsoft/Windows Defender bashers will surely pounce on - regardless how extensive the Beta process is. But hopefully open and unbiased minds will prevail. After all, the goal is to stop the bad guys and if this gets us closer to that, that's a very good thing.
