Sometimes it seems like Windows 8 was designed to make orthopedists rich, because the new OS asks PC users to perform so many unnecessary clicks and mouse gestures. The most blatant waste of time and muscle movement is caused by the cutesy lock screen that you must close by either dragging it offscreen or clicking on it (the faster method) every time you boot or wake your computer.
Tablet users may like to see the weather and time when their devices are inactive, but on PCs, the display is nothing more than a giant roadblock that stands between you and your login prompt.
Fortunately, you can make the lock screen disappear permanently. Just enable the "Do not display lock screen" setting in the under Computer Configuration > Administrative Tools > Control Panel > Personalization in the Local Group Policy editor.
