Microsoft Windows 8.1 Pro is a practical choice for PCs that need the Windows 8.1 environment, including older hardware, touch devices from the Windows 8 era, and systems running software that was built or tested for this version. It keeps the familiar desktop close at hand while adding the Start screen, live tiles and improved app snapping for a more flexible setup.
With the Pro edition, you get the features needed for more advanced home, work and testing use. That includes domain join and Group Policy support for managed networks, BitLocker full-disk encryption, Hyper-V for running virtual machines, and Windows To Go for booting a Windows workspace from a USB drive. It is also suitable for compatibility testing where Windows 8.1 behaviour needs to be checked directly rather than assumed.
