Windows 10: Can't remove account from Windows 10

I have an account on my computer that is from a previous client I worked for and I no longer have access to the account. I want to remove it from my computer to stop getting the message that I have an issue with an account. When I click "Manage" to remove this account, it just pops my current/valid MS account. How do I remove this account from my computer?

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:
   
   Code:

   net user test /del

 

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

 

Strange Windows 10 User Account issue.

Look at this thread,How to Delete a User Account in Windows 10, it may help. You can try the various methods.
Make sure you are using an administrative account when removing the account or log on using the Administrator's account.

Or, if you are patient and know what you are doing, manually remove it.

Either way, Goodluck.
