Windows 10: Locked out of windows account!

After an automatic Windows update I couldn't login to my laptop/Windows account because Windows thought my password was invalid. I tried all the Windows help procedures but they didn't help at all!To check if my password was correct I logged successfully into my Microsoft account in the Internet using an android device. I changed the password hoping that this would synchronise the Windows password but unfortunately it didn't work. The laptop/Windows still insists the password is invalid!Does anyone have a solution to this problem?

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Strange Windows 10 User Account issue.

Unfortunately I had done those steps numerous reboots, it just, reappears for no good reason. The base account isn't even a Microsoft account, it's a local account.

I haven't quite tried the built in administrator account on W10, but so far in my experience on my own computer, the built in account seemed to have absolutely no more control than I did on my own.

It's just strange, I go in, it warns me twice about deleting the account, then it's gone. Reboot, and it's back?

EDIT: Just to specify, both command line and Netplwiz both say only HIS account exists on the computer, it doesn't list this rogue account. This is what I meant in my first post about the fact that even Windows doesn't seem to believe it exists, HALF the time. *Frown

 

Locked out of Win 10 account

Steve, All you need is a Windows 10 installation USB in order to use the procedure given in post #2. If you do not have one of them then you will need to take your computer to somebody who does. The procedure does not entail any use of the MSAccount reset / old mobile number / email reset. Denis
