Windows 10: Turned off Windows Defender, now can't turn it on

I had to turn off Windows Defender so I used gpedit.msc to do this, but now I have no idea how to make it work again. When I open Defender it just shows almost blank interface. If I can open Defender including some more utilities, they just don't work, e.g.: Quick checking utility can be started, but it just doesn't do anything. In services.msc there are also no Windows Defender services. I tried to disable the process which turned off the Defender in gpedit.msc, but it didn't help. Defender doesn't show on the taskbar. Is there any console commands that can maybe help?

Hi Ahmed,

Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

• Type Windows Defender in the Search bar and press
  Enter.
  
• Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
  

Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
Automatic in the Services option. Please follow the steps that we've provided last
September 3, 2017.

Let us know how if you were able to turn it on properly by changing the Startup type to Automatic.
