After shutdown, users are still logged in! (Windows 10)

 This ones been bugging me for a while so I figured it out (thanks Google) this evening.

Situation

• When turning the computer on a second user (or more) is still logged in.
• This occurs even if "Turn on fast start-up" is disabled
• User does not get logged off when rebooting or shutting down
• Logged in users appear as disconnected in the task manager

Cause

The cause is rather a simple one and most people would miss it entirely. One of the account options is as follows:

"Use my sign-in info to automatically finish setting up my device after an update or restart" is switched on.

Remedy

Switch it off!

1. Open Settings
   
   
   
   
2. Choose accounts
   
   
   
   
3. Choose Sign-in options
   
   
   
   
4. Scroll to the bottom
   
   
5. Switch to off
   
   

Why?

One of the main reasons to switch this off is to save a little RAM. If your tight on memory, say running 4GB (upgrade if possible), you may want every ounce you can get!
