Windows 7 comes in two flavors – there’s the x86 32-bit version and the x64 64-bit version. When you buy a Windows 7 DVD, you have the option to install either of these editions so which one should you choose for your computer?
However, if your CPU has a 64-bit processor (like Intel’s Core i5 & i7 series or AMD’s Phenom and Athlon range), you have the option to install both 32-bit x86 and the 64-bit x64 version of Windows.
A major advantage with 64-bit is that it supports more RAM (> 4GB) so if you have any of the ‘big’ software applications (like a video editing software), it should run faster on a 64-bit Windows machine provided the RAM is more.
All software programs written for 32-bit version of Windows should work on the 64-bit version of Windows as well though that’s not true for hardware device drivers.
Drivers designed for 32-bit versions of Windows won’t work on computers running 64-bit versions of Windows. So if you have an old printer with a driver for x86 version of Windows, it may or may not be compatible with the 64-bit version of Windows.
Choose between 32 and 64 bit
First, it depends on the processor that you have on your computer. For instance, if you have a 32 bit processor chip (like Intel’s Pentium or Celeron series), you have no option but to install the 32-bit edition of Windows.However, if your CPU has a 64-bit processor (like Intel’s Core i5 & i7 series or AMD’s Phenom and Athlon range), you have the option to install both 32-bit x86 and the 64-bit x64 version of Windows.

Which Windows Version Do I Have?
To determine which version of Windows is currently installed on your computer, click Start, right-click Computer, and then click Properties.- For a 64-bit version operating system, "64-bit Operating System" appears for the system type under System.
- For a 32-bit version operating system, "32-bit Operating System" appears for the system type under System.
