The road to becoming one with the source is a long and weary one.It is also very rough.Do you want to be able to wield the power or do you want to play around all day with friends?

In other words:...
Your friend cant do anything to you if you dont want him to.
There is no time for fun and games* if you wanna make it anytime soon or even at all.Go code.Leave him to his petty troubles.If you really want to know why not try hakers.com and not gamedev?

*(cept if its you coding them)

This "trick" requires that your friend actually has access to your computer and the authority to run the batch script. Does that give you any clues?

well you can set the attributes of all the files inside your''re windows\system directory to read-only

Or password protect the machine. Or you can tell your friend that, if he deletes all the files on your computer, you''ll give him a smack in the mouth. There is no difference between either the batch script, or deleting everything via explorer.
