Windows 10: W10 can no longer log into MS account

After using my PC for years, I recently started to have a problem with the Windows Store in that it wouldn't sign into my account. After following lots of advice, one of which was to log into my PC using local admin account, I can no longer log back into W10 using my MS account. When I go to settings > accounts > sign in with a MS account instead, after entering the correct credentials it just says "Oops something went wrong it was probably our fault, try again."

My MS account itself is fine - I can log into it using a browser and all seems well, and my laptop is still logged into it and all is fine. When I click on Devices I can see both my desktop and laptop listed. It's just something's happened to my desktop recently which is preventing me from switching back to using my MS account. I don't recall changing any settings which would do this. Any ideas?

Change to which MS account I log in to

My W10 computer is logged into wrong MS account as admin. I would like to log into a different MS account. How can I do this?

 

Local account installation question

I'm fairly certain that Skip this step was available in 10.0.130 - the workaround in Step 20 (back button) is no longer required.

The currently known, as of 10.0.130, ways to create a Local account sign-in are

• Skip this step at the MS account creation phase
• No Internet connection during the install
• static IP (post# 2 by Fragment) - New (to me anyway)

 

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
