    Win 10 Defender doesnt start bc points to wrong subfolder - how fix?


    On reboot of my Win 10 Pro 64-bit machine, the Windows Defender Antivirus Service doesn't start. If I go to services.msc to start it manually, I get an error box that "The system cannot find the file specified". See screenshot:

    What I've discovered by right-clicking the service and looking at its Properties is that this service points to a subfolder that isn't there any more. It fails to point to a newer subfolder in the same folder.

    It currently points to: "C:\ProgramData\Microsoft\Windows Defender\platform\4.18.2008.9-0\MsMpEng.exe" .

    However, the subfolder 4.18.2008.9-0 no longer exists in the folder
    C:\ProgramData\Microsoft\Windows Defender\platform\

    Instead, that folder "platform" has two newer subfolders with the names
    4.18.2009.7-0 and
    4.18.2010.7-0
    Both of those newer folders have the file MsMpEng.exe.

    So, how can I get the Windows Defender Antivirus Service to point to one of those newer folders, ideally the (maybe) newest one with the title 4.18.2010.7-0?

    Failing that, how can I create the missing folder 4.18.2008.9-0 and copy into it everything that is in the newer folder 4.18.2010.7-0? This is a heavily secure area, and the normal New Folder, Rename Folder and Copy and Paste operations are blocked even though I'm in the Administrators group on my machine.

    And I also have exactly the same problem with Windows Defender Antivirus Network Inspection Service, which points to the file 4.18.2008.9-0\NisSrv.exe, except that 4.18.2008.9-0 no longer exists..

    Thanks.

    :)
