How about locking the computer automatically when left idle for sometime? Well that will be very helpful. To lock a computer automatically we don’t need any software or special tools. All we need to do is to set a screen screensaver and configure it to ask for password on resume. That’s a very simple solution right?
In all the versions of Windows Operating systems (XP, Vista, Windows 7, etc), it is possible to configure to activate a screensaver after a desired amount of idle time and ask for password on resume.
The below screen capture of Windows 7 shows the configuration settings required to automatically lock the PC after 5 minutes of idle time(in other versions of Windows the options are more or less same)
I’m not a big fan of screensavers also I consider it’s little annoying to set flashy screensavers at work place. So I choose Blank as the screensaver
