We’ve been quite busy for the past two months or so working through all the feedback we’ve received on Windows 7. It should be no surprise but the Release Candidate for Windows 7 will have quite a few changes, many under the hood so to speak but also many visible. Some have asked if the featureset is "frozen" then what will we change--we change a lot of things in the beta based on feedback and we try to do so in a systematic manner with the focus on the goals for the release. The goal of having a fully functional Beta was to make sure we received reliable feedback and not a lot of "hey this doesn't work at all" sorts of reports. This has allowed us to really focus on delivering a refined RC where the changes we made are all the reflection of feedback we have received.
