How to lock the screen after a particular time
If you want to lock your screen when it’s not in use for a certain amount of time, you’ll need to use a screen saver in Windows. When you set up the screen saver in Windows, you have the option of showing a login prompt when the screen saver is interrupted. This is an excellent option if you want to lock your computer automatically when it has not been used for a specific amount of time.
For the most part, the screen saver settings screen is similar for all Windows versions, but accessing the screen is slightly different. If you are using Windows XP, click the Start button and select Control Panel. Now switch to the layer view and double click on the Display icon. Finally, select the Screen Saver tab.
If you are using Windows Vista and Windows 7, all you have to do is click on the Start button and type screen saver and then click on the Change Screen Saver option when it appears.
For Windows 8, at the Start screen, type screen saver, click the Settings item in the search results, and then click the Change Screen Saver option when it appears.
You will now be at the screen saver settings window, as shown below. It may differ slightly depending on the version of Windows you are using.
To turn on the screen saver that automatically locks your screen, select the screen saver you want to use from the drop-down box and then put a check in the checkbox labeled On resume, display logon screen. Windows will be configured with a screen saver that automatically locks your screen when someone tries to use it.
