Windows 10: How do I remove an unfamiliar device from my Windows 10 account?

I use a laptop computer only, but a Desktop computer is listed as one of my Windows 10 devices. How do I remove it? Microsoft alerted me that someone else may have been using my account and I had to change my password. So I want to make sure that only authorized devices/users have access to my Windows account.

Remove account


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

• Press WIN + X keys and click Command Prompt (Admin) from the menu.
• Type the following command and press Enter. Replace test with the name of your sister's account. Code: net user test /del[/quote]

 

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.
