There is an upgrade function. You're not losing your data or
installations.
really? does it work with the europe-versions? i heard that vista cant be upgraded to 7, because the europe-versions have no internet explorer integrated. so can the rc upgraded to the final e-versions? how is it?
As Frank already mentioned, Microsoft found another solution. The IE is included but will not be installed if you don't want it to.
Thus also the upgrade from Vista to Windows7 works in Europe. (afaik)
