Windows 8 Pro, Upgrade Edition [Upgrade from Windows XP, Windows Vista, Windows 7] (PC)

who wants to upgrade their machine to Windows 8 to first download Microsoft's upgrade advisor. This will check applications and hardware for compatibility with Windows 8. Microsoft also has its own pages called Microsoft Compatibility Centre which lists a vast range of software and hardware which will (or won't) work with Windows 8. Both 32-bit and 64-bit, Windows 8 RT and Windows 7 are also included. Having worked in I.T. for many years (going back to the days of Windows 3.1), and have already installed the pre-releases of Windows 8, I knew what to expect from the upgrade and its new look. My PC is nearly 4 years old with a 320 Gig Hard Drive, 4 Gigs of RAM, 1 Gig Nvidia Graphics card and a USB Wireless adapter.
