Windows 10: Microsoft account is telling me that my Desktop Device Windows is not up to date -...

I have tried to use the Windows Update to scan for security updates to my computer. Something odd has happened.I briefly get an available windows update called "Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 Version 1.339.368.0", however after a split second it disappears and my machine is telling me that my "You're up to date".I am concerned because I believe I believe I have recently been the victim of a Remote Access Tool on my computer.

Unknown devices on my Microsoft account

Hello Flemmingk,

Could these other devices be from friends that you may have signed in to your Microsoft account on for something?

Afterwards to be safe, I would recommend to change the password of your Microsoft account, and enable two-step verification if you haven't already.

Unknown devices on my Microsoft account

Thanks Brink
I get different reactions every time I try to delete a device, but the result is that I cannot remove the devices.
I'll go back to local accounts and delete the Microsoft account.
I changed to Microsoft account because I wanted to use the Continue on PC feature. This feature doesn't work so I think that I'll just forget about it.
Thanks for your interest.

 

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
