Now i found solution for users who are struggling like me. There is no even one post about exact concept of this problem. But one of them really helped me even though it is not fully helps. So there is folder C:\Windows\System32\SecurityHealth. In some cases files there is one folder and one securityhealth.exe file. If you have them go to the folder. File Microsoft.SecHealthUI_8wekyb3d8bbwe.appx open it to reinstall see if it works. For users who do not have it download it from following link:

    Additional thank you to Kapil Arya for providing download link.

    You can also check it online to make sure it is safe. So launch exe file as 

    administrator. Wait command prompt to unemerge. Then you will see the 

    files appeared. Find that appx in folder launch and install. It should be fixed.
