Windows 10: I can't login to my windows account even tho I know the user name and password, it doesn't...

This happened all of a sudden and my PC can't even install any applications. It also doesn't let me run any command or app by the 'Run' app. I'm so tired now! Please help, nothing is working. The login screen with a wallpaper in background etc doesn't appear but only that command prompt like 'Logon UI' appears all the time and it doesn't let me sign in with the actual username and password.

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.

Does it mean my HDD is useless?

 

I can-t login to my account

https://screenshot.it.sftcdn.net/it/...01-700x416.jpg
I know the pin but it does not login. I tried the system recovery but it did not work and I hope I didn-t delete anything by doing that.
This problem started because I wanted to change my account name
C:\Users\name\Desktop
C:\Users\name2\Desktop
and I did that by following these istructions
Rename user account folder
and
Advanced User Accounts control panel
the Managing User Account names from Control Panel dind-t work

now I-m in a temporary account I think
here I can find my original username
C:\Users
and then the name I wanted to change it with.

I-m in trouble please help me!!

 

Changed my Microsoft account password but windows login keeps accepting old password

Hi,

I have a Microsoft account (to be specific, it's a Passport account. I created it with a gmail account) and I recently changed my password and activated two-step verification with Microsoft Authenticator app.

The new password works perfectly in any web page, but doesn´t work when I try to login in my notebook. Windows login keeps accepting old password, and doesn´t accept the new one.

Am I doing something wrong or this is some kind of bug?

Thanks.
