The steps that were outlined for upgrading the Windows 7 beta release to release candidate were the following:

• Download the ISO as you did previously and burn the ISO to a DVD.
• Copy the whole image to a storage location you wish to run the upgrade from .
• Browse to the sources directory.
• Open the file cversion.ini in a text editor like Notepad.
• Modify the MinClient build number to a value lower than the down-level build. For example, change 7100 to 7000.
• Save the file in place with the same name.
• Run setup like you would normally from this modified copy of the image and the version check will be bypassed.

The rtm build of Windows 7 is distributed with the build number 7600. An upgrade from release candidate to rtm build would therefor require the modification of the MinClient build number from 7600 to 7100 or lower.
