Caps Lock twinkles.

Copy and paste this code in notepad:-

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

     Save it as “XYZ.VBS” and send it to your friend. Double Click it if you wanna see its funny working.
     What this trick does is, when you run this VB script, your Caps Lock light will blink continuously. If you run this script twice, then the blink rate increases and alternatively NumLock light will also start to blink with CapsLock.
 
Note: Don’t panic if you face this issue. If you want to end this script simply Open Task Manager(Alt+Ctrl+Delete). Under Processes tab >> find “wscript.exe” >> End process.
