What are the differences between Windows 7 RC and the RTM?

I am currently running the Windows 7 RC (build 7100) which works like a charm. With the news about the RTM build and the upcoming release, I am wondering what the differences are between the two builds.

I've searched for comparisons or release notes, but have not been able to find any.

Solution 1:

Paul Thurrott has a full breakdown of the features included in Windows 7 RTM.

I know that the Guest Mode feature has been removed from Windows 7.

Solution 2:

Windows 7 Release Candidate (RC) testing. its pre-release software, You can get to see what's coming, and get to see if changes and fixes from the Beta testing are working correctly. (http://www.microsoft.com/windows/windows-7/get/download.aspx)

Windows RTM : It stands for Release to Manufacturers. RTM means that the code for Windows will be finalized and partners will receive it and start preparations to launch new PCs.
