This trick uses a simple Visual Basic Script which when activated makes your Scroll lock, Caps lock and Num lock LEDs flash in a cool rhythmic way which gives the perception of a live disco on your keyboard.
3. Save the file as Disco.vbs or “*.vbs”.
Double click on the Saved file to see the LED lights on your keyboard go crazy and make your own cool disco.
This trick has been tested on Windows XP, Windows Vista, Windows 7 and Windows 8 and found to be working perfectly.
You can disable the keyboard disco by starting Task Manager and ending the wscript.exe process.
