It would be correct to assume that 64-bit does more than 32-bit. The difference between 64-bit and 32-bit refers to each processor’s information processing. The option between 64-bit or 32-bit came about in 2001 with the introduction of the Windows XP edition with 64-bit. Windows XP then began offering Professional x64 support for both versions in 2005. From this point on, it was possible to use 32-bit software with a 64-bit operating system. Using a 64-bit software with 32-bit operating systems is not possible.

Operating systems with 32-bit are significantly older and only offer a memory of 4 GB at most. The addressable memory value is phrased in bit and byte. The 32-bit versions have an addressable memory of exactly 2³² bytes. That’s 4,294,967,296 bytes, or 4,096 megabytes (4 GB). On the other hand, a 64-bit system offers a memory of 8 GB, 16 GB, or more. 64-bit versions therefore use their capacities faster and more efficiently. This is also the case with multiple active programs which you can switch between frequently. While 64-bit systems have no upper limit, 32-bit versions can only address 2 GB for each active program.

The right version for you depends firstly on the hardware. Most programs today offer versions with the corresponding compatibility in 64-bit or 32-bit. Programs can also use older 32-bit programs with 64-bit systems, but this is not possible the other way around as we have already mentioned. It boils down to which Windows version you use and which software you want to use, or rather which kind of processor is required.

You should always use 64-bit versions if your system has a 64-bit architecture. This will ensure your programs run smoothly and quickly even when used intensively and in parallel. It may be a good idea to upgrade rebuild your system from a 32-bit to a 64-bit, for example, if you’re running a 32-bit operating system on hardware whose processor can easily support 64-bit. However, you must also update all hardware drivers when you make this switch, or you may risk some system components becoming useless.

Windows 10 offers both a 32-bit and a 64-bit version, while Windows 11 is now only available as a 64-bit version.

Are you planning to install a certain program where you have to choose between the 64-bit and 32-bit version? Or perhaps you’re torn between the 64-bit and 32-bit versions of Windows 10? The first thing you must do is find out which Windows variant you are currently using and whether your hardware is compatible with 64-bit.

Keep reading to find out how to find out your Windows version and see if you’re using Windows 64-bit or 32-bit.

Step 1: Use the Windows shortcut [WIN] + [i] to access the Windows settings and go to “System”.

Step 2: Go to the “Info” option in the “System” menu to display the system information. Under “Device specifications”, you will see information on the 64-bit or 32-bit version and the processor, e.g. “x64-based processor” under the heading “System type”. It is also important to note the installed RAM, which should be at least 8 or 16 GB for 64-bit systems.
