Windows 10: Windows defender doesn't start

Good evening,ultimately my Windows defender window doesn't start even if I try to launch it in some ways.Here's a picture of the problem: - I tried to do a scan of memory of Windows, everything is fine. - I tried to re-install windows, but it's still okay.What should I do?Thank you!

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?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.
