I think what you are looking for is Windows Anytime Upgrade but it doesn't appear to get around the having to do some sort of install though it is supposed to keep your settings.

This post The Windows Anytime Upgrade Experience for Windows 7 at the Windows Team Blog walks you through the process.

That's great news Niek. Now we know that it actually works and doesn't take very long. –  Sim Oct 19 '09 at 13:46

Indeed only with Windows Anytime Upgrade but this is only available from October the 22nd, thus the release. At least, I got a notification (error!) pointing this way

If you're moving up versions, I don't see why not. You can probably do an anytime upgrade too.

You just won't be able to go across bits, so 32-bit to 64-bit (or the other way) is out of the question.

Do you also know how to do this? Can i just enter a new key or do i to download the ultimate edition put it on a dvd and use it for the upgrade. –  Niek H. Oct 19 '09 at 13:10
    
you need the media + a key & yes, you have to run setup to do an upgrade –  Nick Kavadias Oct 19 '09 at 13:17
