Here is how to put Windows
If you are working with a large number of apps open, and suddenly you need a break for 10 minutes or so, the best option is to put your PC in sleep mode.
In the Windows 8 sleep mode, the computer stays ON but uses very less power as compared to normal mode. All your opened apps remain open so that when you come back and awake your PC, you can start your work from the point where you left it off. This is a big advantage over the situation if you have to shut down your PC for 10 minutes and when you come back and boot you PC you have to restart all your apps.

The “Settings” sidebar will show up in the right side of the screen.
Click on the “Power” button. A pop menu will appear, where you can see the “Sleep” button.
Click the “Sleep” button to put your system in sleep mode.
