Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows?

No. If you are currently running a 32-bit version of Windows, you can only perform an upgrade to another 32-bit version of Windows. Similarly, if you are running a 64-bit version of Windows, you can only perform an upgrade to another 64-bit version of Windows.

If you want to move from a 32-bit version of Windows to a 64-bit version of Windows, you'll need to back up your files and then perform a custom installation of the 64-bit version of Windows. For more information, see Installing and reinstalling Windows‍‍.
