Following on from my previous thread, if I've copy (genuine) of XP is there a limit to the number of PC's I can install it on? Been used on 2 so far (I think).

Depends on the license type. Unless its a corporate or volume license then usually just the one. Seeing as its XP tho i imagine you could get away with putting it on several machines with no harm. Still piracy tho 😉

Edit: Yeah thought so:

Q. Can I install my pre-installed copy of Windows on more than one PC?

A. No, Windows is licensed per device (or machine). This means you need one licence for each device that it is installed on. If you want to install Windows on a second machine, you would need to buy boxed software or buy a new machine with Windows 7 pre-installed.
