For what reason you need to check if your Windows is 32-bit or 64-bit

The main reason should be the compatibility problems between Windows operating system and software products as well as drivers. When you download and install software or drivers on your Windows PC, you need to determine whether you should download a 32-bit or 64-bit version of software/driver depending on the versions of your Windows, because 32-bit versions of software/drivers cannot run well on 64-bit of Windows.
