NisLog.dll File Missing

When i attempt to open C:\Program Files\Windows Defender\NisSrv.exe This is the error message i get. NisLog.dll File is Missing, try downloading file again. But I get nothing when I put in the program or the file anywhere on my computer or on the web? But its listed as running under my Taskbar Services.

Try create a USB repair disk and boot with it and try to repair your system file:

is there any changes before this issue happen?

did you installed any other antivirus program? using another antivirus and defender maybe will caused this issue

did you try to perform system restore using restore point (back to condition when Windows defender still working fine)

try to re-register Nislog.dll, type this command at cmd and run as administrator

regsvr32 /u NisLog.dll

regsvr32 /i NisLog.dll

try to run system file checker if still not working

next step will be refresh, reset and reinstall

Hello,

Windows Defender is part of the Windows System. Therefore, we can also try running the SFC to repair it:
