As you know Windows 7 RTM has been released to TechNet and MSDN subscribers yesterday. If you are using Windows 7 RC build and want to upgrade to RTM build, you'll get following error message:
If you can remember, the same thing happened to RC build. Microsoft blocked upgrade from Beta build to RC build. We posted a tutorial to upgrade from Windows 7 Beta to RC build:
How to Upgrade from Windows 7 Beta to RC Build?
The same tutorial can be followed to upgrade from RC build to RTM build. So follow these simple steps:
1. Download the Windows 7 RTM ISO file and extract it using 7-Zip.
2. Now go to "Sources" folder and look for "cversion.ini" file.
3. Open the file in Notepad and you'll see following lines in the file:
4. As you can see the MinClient value is set to 7233 but the public RC build number was 7100. So just change 7233 to 7100 or 7000.
5. That's it. Save the file and run the setup.exe file again. Now it'll allow you to upgrade from RC build to RTM build.

Nice Tutorial.....thanks, now there is no need to reinstall the software and settings...
@PMoto, Yeah you have to activate Windows 7 RTM with a genuine key, if you have. If you are a technet or msdn subscriber, then you'll get the key from there....
RTM have no expiration date as it the final release of Windows 7. you have to pay for RTM build, there are not freely available to download and activate...
