4.5 Not really for XP upgrades robiatti | 15/01/2011 | See all robiatti's reviews (12) I recently purchased a new video card and to run Direct X-11games required the upgrade to Windows 7.I was using XP and found that this package for Windows 7 is not really an upgrade as you will need to back up all your data and have all your installation discs for the applications you want to run. After a clean install of Windows 7 you will then be able to reinstall all your software (some of it may not work on Windows 7!) and then you need to re-import all your data. Hardly an upgrade and you need a big external drive to do this if you have lots of iTunes data etc.Some common programs such as Office may not work on the OS and Outlook Express has been removed completely so you need to use Windows Live Email instead.Had this been obvious prior to install I would not have bothered. I was very disappointed and annoyed with this fact.
