Windows 7: Question: Will Home premium have Compatibilty mode?

I read this: http://www.bestbuy.com/site/olspage....type=category; and on the bottom where it compares the two it says Run many existing Windows XP productivity applications in Windows 7 Is that compatibility mode, or XP mode.

I don't believe so, you will need professional

Compare Windows 7 Editions

Also, will w7 upgrade version be able to upgrade from the RC version of w7

nope

That is xpmode not compatibility mode

If i remember correctly yes but since your running ultimate you could only upgrade to ultimate.

No upgrade path will be offered from any Beta or the RC. You will need to do a 'Clean' Install of the RTM.

Have a look at both of the links here.

You need XP or Vista (or 2000) for the upgrade. The RC isn't one of them.

And I believe the things like Ultimate -> Ultimate only are for the free upgrade option, i.e., if you buy a Vista Ultimate computer now, you can only upgrade to Ultimate for free, etc.

They haven't indicated any such limitation for the plain ol' upgrades. Simply that you need a prior genuine version of XP or Vista (or 2000). It would appear you can upgrade to any version you want as long as you have the prior stuff somehow.

Have a look at both of the links here.

Well now, isn't that just dandy! . . I stand corrected.

And this just proves that your never to smart to learn something new.
