How to switch between users in Windows 8 or Windows 10
To switch between user accounts in Windows 8 or Windows 10, you need to click on your user name or account picture in the upper right-hand corner of the Start Screen. This will open up a submenu as shown in the image below.
When the submenu is open, click on the Sign out option. This will bring you back to a screen asking you to enter the password for the previously active account. Simply click on the left arrow next to the account name to get back to the listing of all accounts on the computer.
As in most previous versions of Windows, you can also still sign out from the security screen you get when you press Ctrl+Alt+Delete.
Note that this is just the security screen you get when you press Ctrl+Alt+Delete, not the actual lock screen. You cannot sign out from the lock screen, so if you’ve locked your computer, you’ll need to enter your password to get back in and then sign out.
