    Hi,
    _Check if windows defender is up to date if not update it.
    _Check if the date and time are correct.
    _Open up services.msc and check if windows defender service is set to "Automatic"
    _If the problem still assist download this tool, it will try to find any error in windows defender then fix it:http://go.microsoft.com/?linkid=9787450
    _If none of this worked, umm... you have to remove it then reinstall it, here is how:
    -press win+x+r then type in: "appwiz.cpl" (without dots) then choose windws defender then uninstall it, after that download newest version of windows defender (am a bit lazy today so just google it) and install it.
    Hope That helps.

    Hi,
    I think you should restore to a later restore poin.
    P.S: Do it in safe mode

    Look at the Action tab, what is it set to?

    Also, I think you want the Windows Defender Scheduled Scan task, not Cache Maintenance.

    Anyway, here is what mine are set to and they work:

    Cache Maintenance:

    Scheduled Scan:
