if you have set a password upon starting up, the lock screen and password lock screen may duplicate its function, as the swiping for lock screen is redundant
to simplify, you can disable the lock screen by following below procedures:
win 8 pro: win button+ r> gpedit.msc> Navigate to Computer Configuration -> Administrative Tools -> Control Panel -> Personalization in the left pane of the window > Double click (or tap) on Do not display the lock screen. Another dialog box appears> Select Enabled and click Ok.
