well
go to run- type msconfig
go under startup tab and see if there is any entry with the name "wmplayer.exe"
if it is , remove it
else , press ctrl+alt+del
and go to processes tab
close wmplayer.exe
hmmm!!!
why not try locking the software folder with a free folder security encryptor file
i mean aggregate all your setup files under one root folder and then lock it using a software!!!
