Windows Defender disabled and is unable to start


OK. I am not sure if you can complete the steps below.......................
In the search box, type services.msc > Enter
Items in the Services box are listed alphabetically.
Scroll down to Windows Defender Service...........................
at Status heading, it should be.................................... Running
at Startup type, it should be......................................... Automatic







If that is not what yours said, right click at Windows Defender Service > click Properties >
can you change the Startup type to Automatic and Service status to Start ?
If yes, do so and click OK when done.
