OPERATING SYSTEM USE FOR ULTIMATE HARDWARE We like to keep Ultimate Hardware users safe so we recently asked our Users which Operating System they use and here are the results. 0% use Windows 8, 7.4% use Windows 7, 7.2% use Windows XP, 2.9% use Windows Vista, 3% use Windows Mobile, 1% use Windows 2000, 1% use Windows ME, 2.2% use Windows 98 and 1% use Windows 95. For none Windows Users the results are:- 2% use Mac OS X, 1% use Ubuntu, 1% use Fedora, 1% use FreeBSD and 1% use Google Android. I was surprised by how low the Windows 8 result was and how close Windows 7 is to Windows XP."
