What is the difference between 32 and 64-bit Windows?
The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) such as those required for high end 3D gaming.
Most Vista computers are 32-bit, but there were some 64-bits also.
To find out if your computer is running a 32-bit or 64-bit version of Windows i Vista, do the following:
Open System by clicking the Start button , right-clicking Computer, and then clicking Properties.
Under System, you can view the system type & it will clearly state if it is 64-bit
If you are running the 64-bit version, you should shop from our Windows 7 64-bit collection instead and check that the System Requirements include Vista.
Many games/programs made prior to Windows Vista require compatibility settings be applied in order to operate successfully. Watch the video below to see just how quick and easy this can be.
