Windows 10: "Microsof Account Problem" pop-up message: what action is required?

I get the following message appearing occasionally on my screen, apparently at random. It appears bottom right of the screen, stays for 20 seconds then disappears. It does not give me sufficient information to make me want to action it, and my system is performing correctly. The content seems incomplete and unprofessional to me so I am suspicious, but if it's not official how could it have got there?


Should I action it, ignore it, or find a way to permanently delete it?

Accounts-Your email and accounts: Attention required - but what?

I have had that error when adding an email account which has 2-step authentication, I required an app specific password, once entered the error message disappeared.

 

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:

 

Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.
