I have submitted many bug reports and feature requests. Since RC was made available I have sent one related to a third party software issue. Microsoft has usually responded very well to each of my reports. You can still send feedback to MSFT Windows 7 team even in RC and RTM builds. Search for "Send Feedback" from the start button. Or you can run this command:
Code:
rundll32.exe FeedbackTool.dll,ShowWizard
Officially from Microsoft on May 16th, 2009:
"Your feedback during the Beta process was very helpful. The "Send Feedback" feature isn't in Windows 7 RC, because we're at a later stage of the software development process. With this release, we're focused on verifying that all the changes and fixes we made based on the Beta tests and feedback are working correctly. We do that by gathering the automatically generated information (called telemetry) that your PC sends us when you use Windows 7 RC. Telemetry provides information about when your computer hangs, crashes or has performance issues, and it lets us know what applications or devices you were using when you experienced problems. It is important that we get this data from thousands of different hardware configurations in order to complete Windows 7. This will help us confirm that the fixes we included based on Beta feedback work on a wide range of hardware, and identify any new problems. "
