I was wondering, Ive reinstalled windows XP on another computer and left it to a friend so he could install Windows XP. but does the Windows XP disk have a certain number of tries before it wont install windows Anymore?

The discs themselves are unlimited, it's the keys that come with the disc/machine that have a limited number of uses (technically). After a certain number of installations with a key, you will have your activation rejected and will have to call up MS to explain the install and get activated. That usually just involves telling them you formatted and you'll get activated.

 

 

 

 

 

 

 

You can use any XP disc with a matching XP key. Any home disc will let you install any home key and so on. It's the activation that matters.
