Are you still on Windows 7 Beta? Then it’s time to move to the Release Candidate since the Beta will expire on August 1st. But already next week on July 1st you will experience issues since the OS will start rebooting every 2 hours.
You can download Windows 7 RC here and give us your feedback via input.microsoft.com
Your link for downloading RC actually points to download of 7100 which is beta!
7100 is actually RC so the link is correct :-)
