I wish it had been what was promoted as on Amazon's product screen, which said it was Windows 7 Home Edition, but go to order and it says upgraded to Windows 7 Pro, didn't know which was correct.After researching the difference between Home and Pro i decided it'd be ok and ordered it. It only has a 232 gb hard dive  to start , then 206 gb hard drive to work with after the computer is ready to be computer. As far as the computer Itself  i'm ok with the hard drive size &  so far it's been a good computer and worth what i paid for it.
