Windows 10: How can I delete a school account that doesn't exist anymore?

So I have my school account from before summer, now that I finished that school, I believe the account doesn't work anymore. I've done everything I can to delete it but it doesn't have the option to disconnect or delete. All I get when I tap on the account is 'Mange' and when I tap there it asks me to log in but it says something is incorrect probably due to the account not work so I can't log in to remove it or whatever. I don't know how to remove it. Any help would be appreciated :

Scanner doesn´t work anymore after last Windows 10 update

As many people on the internet already are discussing, their scanner doesn´t work anymore after the last Windows update. But there seem to be no solution.

My Scanner starts making noises, as usual, and then i get error messages: "Communication with the scanner is not possible"
or this




Is there a workaround for that?

 

How do I delete a Work or School account that does not exist?

I am continuously annoyed when I log into any of a half dozen Microsoft services because when I enter my personal email address Microsoft thinks I am using the same email address to log into both a Personal account and a Work or School account set up by
some IT Department.

This is impossible because I have never worked or gone to school anywhere that would have given me an account using my personal email address. In fact this personal email address didn't even exist before I retired five years ago, moved to Florida, and opened
an ISP account here.

So, I tried to log into that Work or School account to fix the problem. That login was rejected, and after using the access help link with that personal mail address plus captcha, it quit with the error message, "The user ID
you entered does not exist. Please check that you have typed your user ID correctly."

Yes, I presumably have the option with the link https://support.microsoft.com/en-us/help/11545/microsoft-account-rename-your-personal-account,
but this is unacceptable. My primary email address is used to log into a half a dozen devices, into multiple Microsoft services, and into about a hundred other online accounts. In any case, the instructions on that page don't work:

Step 1 goes to my info page,

Step 2 asks me to select, "Manage your sign-in email or phone number."

Step 3 already shows my personal email address and

Step 4 shows that personal email address is already marked as primary alias.

Step 5 to "Select Remove next to your work email address to remove it from your account" cannot be performed because no other work or school email address shown.

So how do I get Microsoft to stop offering a Work or School account that does not exist?

 

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?
