    Cannot turn on Windows Defender virus protection

    I had the same sort of symptoms. In the Windows Security Center, under Virus and threat protection, it said "Your virus & threat protection is managed by your organization."

    I note you mentioned the Registry Keys under HKLM/SOFTWARE/Microsoft/Windows Defender. Nice spotting, but it seems like there is another key that is causing the problem for some users.

    Steps to a solution:

    1. Press the Windows key and type "regedit"
    2. On the regedit icon that appears, right-click and select Run as Administrator.
    3. Navigate to the folder located at HKLM\SOFTWARE\Policies\Microsoft\Windows Defender (You can paste this into the address box at the top of the window, or navigate manually using the side directory structure)
    4. In this folder, there are probably two keys. Right-click and Delete the DisableAntiSpyware key.
    5. Exit regedit, and return to the Windows Defender settings screen (refresh it if necessary). Windows Defender should have the scan options available and working.

    Solution adapted from here, with a much more detailed solution here.

    Virus and threat protection has stopped and will not restart, Windows 10 ver 1709, antimalware client ver 4.12.16299.15 . SuperAntiSpyware installed.

    I have tried most of the suggestions from the support pages, all have been ineffective. Any suggestions

    Virus and Threat protection

    NOTICE: After, installing 1909 update, Windows Defender, Virus and Threat protection, is / was "OFF". IS this common? Is this a bug? NO MESSAGE appeared in my Notification Area.. ONLY, by chance, did I notice, and turn it back on. I'd suggest.. AT
    ALL TIMES.. 'WHENEVER' MY virus protection is turned off.. BY DEFAULT... I 'SHOULD' BE NOTIFIED! YOUR thoughts on this?
