I built my rig in 2010 with Windows 7 32 bit thinking I could run most of my games off of it for a long time until I hit a problem earlier this year when I bought C.O.D Ghosts for PC. I currently have Windows 7 32 bit but from what I hear it is not able to even start up COD Ghosts with 32 bit at all. So my question is which version of Windows 7 Home Premium do I need to upgrade from 32 bit to 64 bit. Do I need the Upgrade version or the system builder version?
Your license is good for both 32/64 bit. So if your cpu is 64 bit you just need a 64 bit dvd/flash drive installer. It will require either formatting and clean imstalling or custom installing Windows. Custom means it will put all the data into a Windows.old folder and you will have to reinstall all software and updates as if it was a clean install but the data will still be on the hard drive.
