Notes on comments.
Welcome to our blog dedicated to the engineering of Microsoft Windows 7
Back in January we released the Beta and updated you on our overall engineering process that will get us from Beta to the Release Candidate. Today, downloading of the Release Candidate started and we’re already seeing a lot of installations and a lot of excitement. On behalf of the team, I want to extend a thank you for all of the millions of people who have been running and testing the Beta who have helped to make the Release Candidate possible. The feedback we have received, through all the mechanisms we have blogged about, has been an incredibly valuable part of Engineering Windows 7. We continue to be humbled by the response to Windows 7. Thank you!
This post is about the path from RC to what we call RTM, release to manufacturing. RTM is not one point in time but a “process” as from RTM we enable the PC manufacturers to begin their processes of building Windows 7 images for new PCs, readying downloads for existing machines, and preparing the full supply chain to deliver Windows 7 to customers. Thus RTM is the final stage in our engineering of Windows 7, but the engineering continues from RTM until you can purchase Windows 7 and Windows 7 PCs in stores at General Availability, or GA.
The path to RTM starts with downloads of the RC. The RC is “done” and what we are doing is validating this against the breadth of the ecosystem and with partners. It means, from our perspective, we have run many tests many times and are working to understand the quality of the release in a breadth sense. We’re all familiar with this as we have done this same thing as we went from pre-Beta to Beta and from Beta to RC. The primary difference with the RC is that we will not be changing the functionality or features of the product at this point—that’s the sort of thing we’ll save for a future release. We’ve gotten tons of feedback on design and features and shown how we have digested and acted on this feedback throughout many posts on this blog. We know we did not do everything that was asked, and we have also seen that we’ve been asked to do things that are tricky to reconcile. We hoped through the dialog on this blog that we’ve shown our commitment to listening and balancing a wide variety of inputs, and how we have thought about the evolution of Windows.
What sort of feedback are we looking for in the RC? We are primarily focused on monitoring the behavior of the product through the telemetry, and of course making sure we did not introduce any regressions in any dimension from Beta quality. One of the things we have done since Beta has continued to beef up telemetry—we’ve put in additional monitoring points in many systems. We’re particularly interested in seeing what devices are installed, drivers that are required, and overall system performance. We have telemetry points that monitor the UI responsiveness of the Start Menu, Internet Explorer (recently posted), Boot, Shutdown, Resume, and across all subsystems. Of course in the final product, this telemetry is optional and opt-in, and it is always private.
There are a series of specific types of reports that we are keeping an eye out for that would constitute changes we would make to the code between now and RTM. Some of these might include:
All of the feedback will be evaluated and whether the issue is with Windows itself or with hardware, software, or OEM partner code we will work closely across the entire ecosystem to do what is necessary to deliver excellent fully integrated PCs. This goal is more important than anything else at this point. The depth of this work is new for the team in terms of spending engineer to engineer time across a broad range of partners to make sure everyone is ready together to deliver a great PC experience.
Overall, while many have said that the quality of the Beta was on par with past RCs (remember how some even suggested we release it as final!), we are working to do an even better job with Windows 7. We think we have the tools in place to do that.
While the RC itself was compiled about 2 weeks ago, it takes a bit of time to go through the mechanics of validating all the ISOs and images that are released. In the meantime we continue doing daily builds of the product. The daily builds are incorporating code changes to address the above types of issues that impact enough customers that on balance the code change is more valuable than the potential of a regression. Throughout this process, every change to the code is looked at by many people across development and test, and across many different teams. We have a lot of engineers changing a very little bit of code. We often say that shipping a major product means “slowing everything down”. Right now we’re being very deliberate with every change we make.
The RTM milestone is not a date, but a process. As that process concludes, we are done changing the code and are officially “servicing” Windows 7. That means any subsequent changes are delivered as fixes (KB articles) or banked for the first service pack. Obviously our ability to deliver fixes via Windows Update has substantially changed the way we RTM and so it is not unreasonable to expect updates soon after the product is complete as we have done for both Windows XP and Windows Vista.
Between now and the RTM milestone we will make changes to the code in response the above inputs. We are decelerating and will do so “gracefully” and not abruptly. We do not have a “deadline” we are aiming to meet and the quality (in all dimensions) of the product and a smooth finish are the most important criteria for Windows 7. In addition, we have a lot of work going on behind the scenes to build Windows 7 in nearly 100 languages around the world and to make sure all the supporting materials such as our Windows web site, SDK, resource kits, and so on are ready and available in a timely manner.
Once we have entered the RTM phase, our partners will begin to make their final images and manufacture PCs, and hardware and software vendors will ready their Windows 7 support and new products. We will also begin to manufacture retail boxes for shipment around the world. We will continue to work with our enterprise customers as well and based on the RTM process the volume license products will be available as well.
Delivering the highest quality Windows 7 is the most important criteria for us at this point—quality in every dimension. The RTM process is designed to be deliberate and maintain the overall engineering integrity of the system. Many are pushing us to release the product sooner rather than later, but our focus remains on a high quality release.
Ultimately our partners will determine when their PCs are available in market. If the feedback and telemetry on Windows 7 match our expectations then we will enter the final phases of the RTM process in about 3 months. If we are successful in that, then we tracking to our shared goal of having PCs with Windows 7 available this Holiday season.

I started using Windows 7 RC today, I was mainly worried about my software running on it, (Which it does, very well thankfully).
It was a pleasant surprise, it installed onto a clean drive very quickly, it is not cluttered like Vista, in fact despite the flashy interface, it feels like running XP as it should be and looks like Vista should have. It recognized all the hardware with no difficulty except the cable modem but it accpeted the old drivers with no problem.
I took to windows 7 RC really quickly and think it is the best you have come up with to date. If the final version is like this, it will probably end up like XP and Windows 98 did, the version of windows everyone wants to keep using.
This feature is especially helpful to handicapped individuals who do not have the dexterity needed to press the mouse keys in the normal fashion. Presently, programs like AutoHotKey are required to achieve the needed functionality with Window XP.
shutting down the PC after a specified time period, then when you turn it back it, it goes into "Resuming Windows". I prefer this setup because it also allows me to boot into the primary OS (Ubuntu) and do what I need to, and even after restarting, W7 still goes into "Resuming Windows".
Just an issue that I and at least one other Acer Aspire One user has experienced: When booting, boot fails, Windows 7 initiates startup repair, but cannot repair. I
When resuming from sleep/hibernation, any computer with more than 1 video output option (such as a laptop with external monitor port, or desktop with multiple video outputs), many times when it resumes, it resumes to an unused video output, rather than the primary monitor.

I think all users of the operating system windows 7 will be in the comfort of a better vistadan and xp operating system I'm sure the future thank you thank you microsoft blogger
I must say, this Windows 7 is what Vista might have been. I think people expectations will be exceeded. Hopefully you will be able to keep Google's new OS at bay!
windows 7 is going to rock!! i'm going to get it
thanks for sharing..

Since acquiring a new PC with Windows 7 installed, the UI preferences tool on my Photoshop CS4 will not work and the text and icons remain uncomfortably small. Is this connected to the subject of this blog?
i cant wait to see it!
Well I have finally made the leap and found it quite comforting in terms of everythings location. It was nothing like the pain of upgrading from other versions.
I particuallary like the way I can stream music from Media Player 12 to my xbox downstairs - nice.
