Windows 10 comes with a Lock Screen feature in addition to the Logon screen where you type the password. It is an additional screen which is displayed with a fancy background and some useful information like clock and date. It appears before you can pick a user account to sign in. When you lock your computer, again you will see the Lock screen. Microsoft removed the ability to disable the Lock Screen in Windows 10 Anniversary for Pro and Home users. Here is a freeware tool which will allow you to disable the Lock Screen feature in Windows 10 Anniversary Update version 1607.
