Inspired from Windows Phone 7 UI, Microsoft introduced metro user interface and Lock Screen in Windows 8. Lock Screen includes a beautiful background image with date, time and some notification icons, this lock screen appears before you login or when you log out of or when you lock your PC.
We’ve covered how to set custom image as lock screen background, Lock screen allows touch-screen enabled users to login with pin code or by using picture password, so this lock screen is more useful for touch-screens than for PC users as I feel, and lock screen adds one more step or hurdle to pass for us to login, go productive! We can easily disable lock screen in Windows 8 by using group Policy editor, here is how.
Disabling lock screen in Windows 8
1. Using Run command press Win +R to open it and type gpedit.msc
2. Once Group Policy Editor opens, navigate to Computer Configuration > Administrative Templates >Control Panel > Personalization
3. On the right pane, select and double click on “Do not display lock screen” setting and select Enabled option and click ‘OK’ to save the changes.
4. Exit from Group Policy Editor, now lock screen has been disabled. To get the lock screen back, follow steps from 1 to 3 and select “not configured” option for the setting.
Update October 02, 2014: The above instructions to disable lock screen works on Windows 10 also.
