Windows 7 Freezes Up

Since past few days my Windows 7 PC started freezing while using "Windows Photo Viewer" locking up the entire system, I was able to move my mouse and the audio-player continued playing music but Ctrl-Alt-Delete, launch of any application, or shutdown/restart the computer did not worked. The system just froze and the only solution was to do a restart/shutdown using physical power buttons, thankfully we can get rid of this bug using two methods as demonstrated ahead.
