Click on this and this should open a window with a plethora of information regarding your system.The one we are interested in is the System Option. Under the System and Security tab, you will see many options such as Security and maintenance, windows firewall, System.Once on the control panel look for System and Security which has a shield as an icon attached to it.

This will open the control panel which is used to view and change system settings.

Click the start button and type ‘control panel‘ then click enter to search.

One of the easiest ways to check your processor architecture is to head over to the System Option. There are many ways to figure what your CPU and OS architecture within the operating system itself. How to Check What is My Processor Architecture? In any case, below we will check how to check what is your processor and operating system architecture. Here it would not matter if you have a 64 bit CPU, the operating system itself will be the bottleneck. However, if you have a 32 bit Windows installed on your PC, then your system will conform to 32-bit. Most of the CPU made after 2003-2004 actually conform to the 64 bit architecture. People often confuse operating system architecture with that of CPU. In other words, 64 bit archtiecture is backward compatible but the 32 bit architecture is not forward compatible.Īlso Read: Where is Motherboard in Device Manager? Operating System vs Processor Architecture A 32-bit software CAN work on a 64 bit architecture, but a 64 bit program CANNOT work on a 32 bit architecture. In addition to that, depending upon the type of architecture, you will need to install the relevant software. If you install any more than this, the extra RAM will go to waste. In other words, if you have a processor with a 32 bit architecture, you would only be able to install about 4.3 GB of RAM Theoretically (~3.5 GB Typically Usable). Therefore, one of the primary differences between a 32 bit and a 64 bit processor is that the former can only handle 2^32 or 4,294,967,296 bytes of RAM (~4.0 GB of RAM), the latter can handle 2^64 or 18,446,744,073,709,551,616 bytes of RAM (~18,446,744,073 GB of RAM)! The higher the bit of the CPU, the more memory it can address.
