We already know how to upgrade from XP to Windows 7 from our recent post. Today what we have here is how to do a fairly easy installation in-place upgrade from Vista to Windows 7.
The in-place upgrade works when you have a Vista Home Premium you can upgrade to Windows 7 Home Premium same with other flavors of Professional and Ultimate versions. Apparently, besides from that, like when you do Vista Home Premium to Windows 7 Professional this will requires the hassle of clean installations.
Anyways head on CNET, to see the complete details of the upgrade process. I would also suggest a clean installation like what some computer experts think, so you could have a fresh system that works better, otherwise just do the no-hassle upgrade with no possible data loss and re-installation of your old applications.
