The Lock Screen in Windows 8 is a new feature that provides several information to the end-user. First it is optimized to work well in touch-enabled devices and on desktop computers; second, it provides basic information like date, and some system notifications including email, network and battery; and third, it includes an image which you can change at any time to make it more unique.
There are going to be times when such a feature may not be necessary and the simple logon screen is just enough. If this is what you want, you can then follow these steps to disable the Lock Screen in Windows 8 and have faster access to the logon screen.
1. Use the +R to bring the Run command, type gpedit.msc and hit Enter. This will start the Local Group Policy Editor that is extremely useful to control many Windows settings.
2. From the left pane, navigate through: Administrative Templates > Control Panel and select Personalization. In the right side you’ll have all the settings that you can control in this section.
3. Choose “Do not display the lock screen” setting and double-click it.
4. As you noticed, this policy setting controls if the lock screen in Windows 8 appears or not to all users. This is pretty similar to the Ctrl+ALT+Del feature in Windows. Check Enabled, then click Apply and OK.
And that is all there is to it. To test you can just use the +L keyboard shortcut to lock the screen and verify that it works. Then just enter your password to return to the desktop.
