From CNET News.com: Going from Windows Vista to Windows 7 is relatively straightforward. So one might think that moving from a pre-release version of Windows 7 to the final version would also be simple. One would be wrong. That's because the upgrade versions of the Windows operating system (the cheapest way to move to the final version) check for a previous paid version of Windows on the drive. That means, if a user did a clean installation of Windows 7 on their test system (as recommended by Microsoft), that same user will have to back up their data, reinstall their original operating system (XP or Vista), then install Windows 7, restore their data, and then reinstall their applications. For testers who were running XP, that means doing a clean installation of Windows XP over their Windows 7 test build and then a clean installation of Windows 7 over that. Vista users have the option of reinstalling that operating system and then doing an in-place upgrade or a clean installation of Windows 7. View: Article @ Source Site |
