Identifying your system type is also important when upgrading. If you're running a 32-bit version of Windows, upgrading to 64-bit can help unlock the full potential of your computer.

It also happens when running a command in the CMD to install an app. This happens even when the same programs or executable files have run on the same or other 64-bit Windows 11/10 PCs.

As well as running 64-bit apps on 64-bit systems, it also allows 32-bit Windows apps to run on pure 64-bit OSes – even OSes such as macOS that won't run their own old 32-bit binaries.

I have a Dell Poweredge 2950 with a Xeon e5420 CPU with Ubuntu 8.04 64-bit installed. I'd like to use VMWare player on this machine to run a 64-bit image, also with Ubuntu 64-bit installed ...

Further, the Venue 11 Pro in the 64 bit mode sports an Intel Haswell chip, which has made the tablet a tad thicker and heavier than one running 32 bit Windows based on the Intel Bay Trail chip.
