Hi! I just finished upgrading my Windows 7 RC to the final version, and everything is working as expected. No visible changes in the UI or any other areas, still rock solid and FAST! This is (by far) the best desktop Windows version I had the placer to work with. I know there is no "supported" path for migrating from the RC but with a little trick (found through BING, hint: involves touching a cversion.ini file in the "sources" folder in the installation DVD) I was able to do it.
