  • Which version of Windows should I install: the 32-bit or the 64-bit version?

To install a 64-bit version, you need a CPU that is capable of running a 64-bit version of Windows. The benefits of using a 64-bit system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. In such cases, because a 64-bit system can handle large amount of memory efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.
