Windows 10: Windows Defender doesn't exist after update to windows 11

i recently upgraded to windows 11 from windows 10 and when I checked security windows defender isn't there for some unknown reason.

:)

 

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

SEtting up automatic updates for windows defender on windows 8

I have found this on the internet en have set up a task for automatic definitions update for Windows Defender but a window pops up when this starts to run.
Is there a way to set this without any window popping up so that it just runs in the background?

Now I'm using
"C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC

I'm currrently using it as described here:

Why won't Windows Defender not auto update anymore

I have have windows updates set to notify updates , I will install myself, because I want to make a system restore point before installing updates.

Because of this windows defender does not update automatically and I had to create a task for updating in the task scheduler, which I did but it does not work anymore since I re-installed windows.
What am I doing wrong?
