Windows 8: How To Lock Screen And Turn Off Display
One of the problems that I have encountered when using Windows 8 on tablet pc is to lock the screen and turn off display. Android and iOS machines normally have power buttons which would do the job. However the power button for windows tablet (mine is Acer Ultrabook) is limited to sleep and hibernate mode. These modes stop the system including ongoing tasks such as downloading process. There must be a way to lock the screen, turn off the display but at the same time allows ongoing processes to continue until they are complete.
The following tutorial helps you to add this function to your desktop context menu. However, you are expected to have some basic skills in windows file management in order to follow the steps. Beware, if you do not follow the steps properly, you may corrupt your windows registry!
I have tried it out and it worked on my tablet.
