I was also a little confused by the OP on this one. I assume it must be a mistype, as the way it's worded they're putting RC/RTM together as though you might want to 'upgrade' from RTM to the Final. Obviously you can't 'upgrade' from the RTM as it's the exact same thing as the Final. The only distinction is that RTM is when the product is finalised, and shortly after is made available to OEMs - Final is when the same version hits the shelves for the public to buy.
"RTM" and "Final" are tossed round interchangeably...... They refer to the same thing (keep reading). One would not upgrade from RTM to Final or anything else for that matter. When the final builds are voted on and approved, probably 7300, they will be what is available in the stores and on TechNet, etc. and will be referred to as RTM or Final. The issue will be whether you can upgrade any of the RC's or Beta's to RTM, likely Build 7300. I content where there is a will their is a way. The main issue is why? Any upgrade (other than upgrading to itself to avoid having to buy the "Full Version") leaves stuff around from the previous build. A clean install is the way to go since that will hopefully be the last install you do unless you crash or get a new machine. Again, I intend to fully explore the upgrade from RC to RTM just to see if it can be done but I'll ultimately do a clean install.
They say there is a way to upgrade the RC to the RTM.

While there is almost surely a hack to do it... you are so playing with fire. Why go through that nightmare if something goes wrong? Clean install and backup your documents...
Dropbox - Home - Secure backup, sync and sharing made easy.
2GB free online storage... sync to any computer (this is not a paid endorsement)
Please be advised that I wasn't suggesting that anyone should do this. I just found it and thought it might be of interest to people here. I always do clean install. That way there are no screw-ups carried over to the new operating system. Beside that I almost always decide to leave out programs that I had installed in the past because I found something better or just didn't like them.They say there is a way to upgrade the RC to the RTM.
How to Upgrade the Windows 7 RC to RTM (Final Release) :: the How-To Geek
Please accept that you are not understanding this correctly. I am Microsoft Partner and an Invited Microsoft Beta Tester for both Vista & Windows 7. As such I was given both Vista RTM & Windows RTM as \"thank-yous\"... point being, I first hand know what you are referring to & what I'm talking about. I, even think I know the letter you mention but, you have not interpreted things correctly.
You cannot \"upgrade\" from RC to RTM!! Hell, it was even advised, if not begged, that ppl not \"upgrade\" from Beta to RC and they were both betas... RTM is not beta!!
What the letter said was, as of Aug. 6th RTM was available & Beta Testers could \"move to it/migrate to\" it after the RC... not upgrade to it, sure not in the sense you are using the word.
1, it is unacceptable (high risk) to go beta to non-beta when an OS & 2, RC gives no purchased license... either refer back to a Genuine, already owned Vista or XP (to upgrade) or Clean Install a non-beta... since Microsoft or specifically the Windows 7 Build Team gave RTM, w/ it they also give a key (different 1 than you had for the betas) leaving no excuse not to do a Clean Install, even w/out referring back to a previous (genuine, non-beta) OS.
Upgarding from a beta OS to non-beta OS does not even come into the picture... it is not an option!
The 2 links below relate. The 2nd has to do w/ data migration during OS deployment & installation

I received a email from Microsoft telling me we will be able to upgrade from the RC to the RTM version when we receive the RTM upgrade. We already have a bonafide system or we wouldn't have been able to download the RC in the first place. Nothing illegal about it at all. Instructions for a custom or clean install as well as upgrade will be included with the new disc. Also 32 and 64 bit systems will be included in the same purchase and the activation code will be the same for both systems. I don't know if they will be on separate discs or on the same one, but seems like a lot of data for one disc. They say this is a little payback for our help in developing the new Windows 7 OS.
I was afraid we would have to reinstall our previous version of Vista Home Premium before we could do the upgrade. I will probably opt for the clean install so I can get rid of everything that might interfere with the new OS. Windows and HP are pretty good at updating the system so I'll go that route and let them find and install all the drivers and upgrades as necessary.
