Below that question he blogged about the tools you can use for migrating from the beta to the Release Candidate. He used the same tool I described a few weeks back. At the end of hist post he asked for Feedback the Windows 7 Release Candidate through a (new?) Microsoft website called Input.Microsoft.com.
When you log on to the website (first you have to sign in with your Windows Live ID) you’ll see a screen (like below) where you can select Windows 7 Scenarios.
In the fist screen you have to set your local preferences. When you selected them you are able to give your feedback about the operating system. Isn’t that cool or what?!
I think it’s cool that Microsoft is giving us (the users of Windows 7) another possibility to give feedback about the new Windows 7 Operating System!
