I'm about to purchase a laptop and was wondering if I need an operating system as I have windows 7 pro from when I bought the below, Can I use it on 2 systems?
Naughty naughty but yes....no....yes....the licence is for one pc, however you may want to reinstall your windows 7 at some point on a different HDD you install.
No it is a 1 license OS well they all are but you might find it will only work on your original system anyway so i am saying if you get another system you will need another copy of windows 7.
