OS Guide
32bit or 64bit?
32bit versions of Windows 7 are restricted to accessing a maximum of 4Gb physical memory - bear in mind that this includes all memory addresses in your system, so installing 4Gb RAM in a PC with a 512Mb graphics card would only show 3.5Gb available since the graphics card (and perhaps other devices with RAM) would use up some of the memory address space. 64bit versions support 128Gb RAM and perform slightly faster on processors with 64bit instruction sets, at the downside of having poorer driver compatability. Now though, this is less of an issue with Windows 7 being the 3rd generation 64bit Operating System, typically only significantly older hardware and software does not work with it. What's the difference between the different versions of Windows 7?  | Home Premium : Faster Performance, Improved Desktop Navigation, Internet Explorer 8, Improved networking and Home Group support, Windows Media Centre for TV recording / viewing |
|  | Professional : As Home Premium, but with Windows XP Mode for increased compatability and domain login support |
|  | Ultimate : As Professional but with automatic backup facility, Bitlocker data protection and support to switch between 35 languages. |
