Actually i have developed this trick in the vb script. so follow the steps below:

1. Open Notepad.
2. Copy and paste the below text there.

Set wshShell =wscript.CreateObject(“WScript.Shell”)
wscript.sleep 100
wshshell.sendkeys “{CAPSLOCK}”
wshshell.sendkeys “{NUMLOCK}”
wshshell.sendkeys “{SCROLLLOCK}”

3.Save the file as whatever name u wish but with a .VBS extension.
eg. Disco.vbs

Now If You need To disable This:
Press: ctrl+alt+del, on ur desktop.
Search For ” wuscript ”
And Click on end process
