Here below I am listing down the advantages of having a 64-bit windows operating system for your computer.

Advantages or Benefits of 64-bit Windows OS

Here are some good reasons that will tell you on why you should switch to 64-bit version of Windows Operating System for your new or currently working computer given that your CPU supports 64-bit Instructions.

New Advanced CPU Architecture

Newer CPU’s that are coming today are all 64-bit ready and gives better performance with 64-bit OS. This is because of the advancement of technology and thus the CPU Architecture. The newer architecture of the modern day processors or cpu are more suited or optimized for 64-bit operating system. So if you want maximum performance from your CPU then you should install 64-bit Windows OS on your computer.

Supports more RAM

You can install maximum of 4 GB RAM on 32-bit version of Windows and of which only 3.5 GB can be used by the operating system. But in 64-Windows you can add and use more than 4 GB of RAM to your computer that ultimately results in better performance and faster processing. The maximum of amount of RAM that can be installed on 64-bit computer depends upon various factors like Motherboard capability, CPU and various Editions of Windows OS i.e. Home, Professional, Ultimate etc.

The theoretical limit for RAM for 64-bit computer is 16 Exabytes. The RAM limit for Windows 7 OS for its various editions or flavors is mentioned below:

Maximum RAM supported by Windows 7 64-bit

Windows 7 Starter -> 8 GB

Windows 7 Home Basic -> 8 GB

Windows 7 Home Premium ->16 GB

Windows 7 Professional -> 192 GB

Windows 7 Enterprise -> 192 GB

Windows 7 Ultimate -> 192 GB

Better Performance

If you have the right hardware for running a 64-bit OS then it will perform much better as compared to a 32-bit OS with the same hardware. A 64-bit computer having 64-bit OS can handle and process more instructions at a time as compared to a 32-bit computer. Therefore a power user always uses a 64-bit operating system because of the heavy duty processing intensive tasks he has to perform.


Now almost all the latest big games are coming in 64-bit version only, so if you are a hardcore gamer then you have to install 64-bit Windows OS to play these latest PC games as they are not made for 32-bit OS. The main reason for these games to shift towards 64-bit operating system is because companies or developers now wants to create games with high end graphics and advanced realistic effects, and these things will require more resources which can only be possible using 64-bit OS.

Future Proof

You computer will remain more future proof if you already have 64-bit OS installed on your PC, as now most of the applications and games are optimized and made for 64-bit windows only. You can still run 32-bit softwares or applications on 64-bit version of Windows in 32-bit compatibility mode but you cannot run 64-bit applications or programs on 32-bit Windows OS. So having a 64-bit Windows proves to be more advantageous than a 32-bit OS.
