32-bit Operating system

Microsoft Win32 uses the x86 processor in 32-bit flat mode. Therefore, a x86-based version means a 32-bit version operating system.

System Requirements

To use a 64-bit version of Windows Vista, you must have a computer that has a 64-bit processor. Also, you must have 64-bit device drivers for the devices that are in the computer.

Advantages of 64bit Windows

  • a 64-bit version of Windows Vista supports from 1 GB of RAM to more than 128 GB of RAM.
  • Increased program performance for programs that are written to take advantage of a 64-bit operating system

What to consider when you are installing 64bit OS?

  • 64-bit device drivers may not be available for one or more devices in the computer.
  • 32-bit device drivers are not supported.
  • 32-bit programs may not be fully compatible with a 64-bit operating system.
  • It may be difficult to locate programs that are written specifically for a 64-bit operating system.
  • Not all hardware devices may be compatible with a 64-bit version of Windows Vista.
