How to Change From 32 Bit to 64 Bit for Windows Vista Home
If you are using Windows Vista and your computer has a 32-bit processor, you may be interested in upgrading to the 64-bit version of Vista. A 64-bit processor can handle more memory and make a computer run faster in some cases. This can be helpful if the computer is a server or if you need to use a lot of programs at once. The 64-bit version of Windows Vista operates faster and more efficiently on computers with a 64-bit processor. You can get the 64-bit Windows Vista installation DVD from the Microsoft website.
