Windows HD

Windows HD is a series of operating systems by Microsoft as an extension to the Windows series that puts the resolution in HD. It was scarcely distributed, and so it was also scarce to see it being used. Eventually, when Windows mainly started supporting HD, Windows HD became merely an "extension pack" to the current versions of Windows with new features.
