Let’s say your existing Windows computer is running XP, Vista or Windows 7 and you want to upgrade to Windows 8.
This is an upgrade so you’ll be overwriting your current version of Windows but before you take the plunge, please note that your existing software programs will only be preserved if you are moving from Windows 7 to Windows 8. If your PC is running Windows XP or Vista, all your files and data will be preserved but you won’t be able to use the software apps after upgrading to Windows 8.
