[SOLVED] Windows Defender \ Security missing

[makrarom]

Found out a couple of things, while messing with Windows Defender:

1) Windows Defender not found in Services

2) Windows Defender folder in Regedit is empty when there should be DisableAntiSpyware registry there

3) Clicking on Virus & threat protection opens up this message

I've tried googling and solving this myself, and people refer to problem 3) with solutions that are connected through 1) and 2)
Someone even said I should try system restore, but I doubt that'd bring registry back or change my Windows Defender.

Is this crucial to even try to make it work?

Actually in first picture, there is Windows Defender Security Centre Service, but it is running. Nothing else to do there.

Well, windows defender is the anti-virus that comes with your system but it is not extremely crucial to get this working.

This might be a link to download Windows Defender again and see if the files for it pops into those places

If this does not work, you don't need windows defender as there is some other ant-virus software that do a fine job as well. I would recommend Kaspersky or Malwarebytes. Just don't use both at the same time because that would block it out.
