In a posting to its Engineering Windows 7 blog on Thursday, Microsoft outlined some of the changes that will be made for the next public version, which will be a near-final "release candidate" build. However the list does not include the fix for UAC and the MP3 fix, as it is only focusing on visible changes, and furthermore, it is only a sampling of them. That means that the release candidate will include much more than just the 36 visible changes presented, but under-the-hood improvements as well.

"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. 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," wrote Chaitanya Sareen, senior program manager at Microsoft.

The Windows team separated the updates into nine categories, including the desktop experience, touch, and Windows Media Player. Moreover Microsoft has incorporated its "Aero Peek" window transparency tool to the ALT+TAB function to give you a better idea of the items you have open on your desktop. The team has also combined the launch and switch function of the Windows Logo button.

In addition and as it had already committed to, Microsoft is making some changes to the User Account Control feature, following concern that efforts to make the feature less annoying had also made it less secure.
