The terms 32-bit and 64-bit basically refer to the way a processor in a computer, the CPU, handles information. These are also used interchangeably with x86 and x64, referring to their respective architectures.
Obviously, the 64-bit version of Windows 10 is slightly faster than the 32-bit variant, and can also access more than 4GB of RAM, unlike the 32-bit one.
But how to determine, which version of Windows 10 you have installed?
This short tutorial shows you how to find out which version of the operating system you are running.
The easiest way to determine your system type in, well, System.
Open System by pressing the Win + X combination to open the Power Menu, and selecting it in the menu. Here, look to see whether your system type is either 64-bit or 32-bit.
You can also find out this information is opening the Settings app, and clicking on the System icon.
Now, click or tap on About on the left side, and Windows 10 will provide you with the full details of the hardware capabilities of your system. Including, whether it is a 64-bit OS or a 32-bit one, along with the processor, in the System type section.
It is also possible to determine this information in System Information. Just type msinfo32 in the search bar, and press Enter. A System Summary will be displayed on the left side, and the System Type in the right pane will clear whether you have an x64-based PC or x86-based.
And finally, typing systeminfo in Command Prompt also displays this information.
In case you’re wondering, you cannot upgrade from a 32-bit installation of Windows 10 to a 64-bit one. Instead, you must do a clean install, since upgrading is only possible with the same version.
