Since for some reason I can't post in the Windows 7 forum (don't have the right permissions, it says), I'm posting this here instead. So...

Unless I've been reading things wrong, it looks like Windows 7 will be shipping in multiple versions just like Vista. Unlike Vista, Windows 7 apparently has all the features in a single SKU, which means that even if you have the Starter edition, all the features of the Ultimate edition are already installed but not activated. In order to activate or unlock another edition, you'll need to use the Windows Anytime Upgrade (WAU).

Just as proof that this is real, here's a quote from Brandon LeBlanc on the Windows Team Blog:



Now, I don't know about you, but this looks like unnecessary bloat to me. After all, your PC's space and resources will be taken up by features that you'll probably never use unless you upgrade. Seriously, Microsoft, if you thought people gave you flak about Vista...

All very well and good until someone finds a way to crack WAU.
And I agree, it is totally unnecessary bloat; if someone pays to upgrade then they should get sent all the upgrade utilities, then the rest of us dont have to owrry about tens of gigs of stuff we'll never use.

Seems like you were not in the WAU section of your computer an took a look on it.

After registering my computer, I did and the sections show that if you upgrade, you have to download the upgraded stuff.
It is even shown what is coming with that upgrade. I looked through it, noticed I did not need anything of it and just said "no".
