Turn Off all Frustrating System Beeps.

Normally ur laptop gives you a warning beep before EMERGENCY shutdown!  But suppose u r in a Library. Then These Beeps can be very Frustrating. I'm just providing a little tweak to turn off this shit OFF!
Actually i will not annoy u much with my useless speech. Here's the process:

Start
Run
Type " regedit "
go to  HKEY_CURRENT_USER\Control Panel\Sound


Now Look in the right panel. Click the string named as " beep "
Change its value to NO.


You are done.
If you need the beeps again, change the value to YES!


Enjoy!
