    To be honest, doing an in place upgrade (esp. from Windows XP) does more damage then good. Backing up your data and using the Transfer Wizard before doing the clean install, both on Windows XP and Vista brings much better results. A clean install gets rid of all the cruft left behind, a fresh beginning.

    Windows Vista Home Prem x64 can do an in place upgrade to Windows 7 Home x64 or Ultimate. Says so right in the chart. But upgrading from 32bit to 64bit is not possible because it is a completely different OS architecture, applications cannot be safely transferred over. It is just better to start fresh when moving to a 64bit system.

    My advice...forget in place upgrades, do clean installs every time. You also may want to read the series Paul Thurrott did for updating. http://www.winsupersite.com/win7/win7_upgrade.asp
    Logic without the fatal effects.

    That will be my route, a clean install no matter what. I can foresee many getting turned off in upgrading to Windows7 because they will have to do a clean install. Either that or they will wait a while before doing the upgrade.

    I don't see the point in the Ultimate edition of Windows 7 to be honest, unlike Vista there isn't a lot of difference... apart from the language packs, bitlocker and some enterprise tools, it's no different (apart from the considerable price difference) than Professional.

    I have done alot of windows installs in my day, and I have never done and in-place upgrade outside of disaster recovery scenarios where the point was to get something up and running fast before going to tapes or something. Even in those cases, we were also building a new box to transition stuff to while we were in-place rescuing.
