Windows Vista Team Blog : Windows 7

Why 7?

Mike Nash — Tue, 14 Oct 2008 20:30:00 GMT

There's been a lot of lively discussion since I confirmed yesterday that the official name for the next version of the Window client operating system will be "Windows 7" about how we got to the number "7."

I'll say up front, that there are many ways to count the releases of Windows and it's been both a trip down memory lane and quite amusing to read all the different theories about how we got to the number "7."

Anyway, the numbering we used is quite simple. The very first release of Windows was Windows 1.0, the second was Windows 2.0, the third Windows 3.0.

Here's where things get a little more complicated. Following Windows 3.0 was Windows NT which was code versioned as Windows 3.1. Then came Windows 95, which was code versioned as Windows 4.0. Then, Windows 98, 98 SE and Windows Millennium each shipped as 4.0.1998, 4.10.2222, and 4.90.3000, respectively. So we're counting all 9x versions as being 4.0.

Windows 2000 code was 5.0 and then we shipped Windows XP as 5.1, even though it was a major release we didn't' want to change code version numbers to maximize application compatibility.

That brings us to Windows Vista, which is 6.0. So we see Windows 7 as our next logical significant release and 7^th in the family of Windows releases.

We learned a lot about using 5.1 for XP and how that helped developers with version checking for API compatibility. We also had the lesson reinforced when we applied the version number in the Windows Vista code as Windows 6.0-- that changing basic version numbers can cause application compatibility issues.

So we decided to ship the Windows 7 code as Windows 6.1 - which is what you will see in the actual version of the product in cmd.exe or computer properties.

There's been some fodder about whether using 6.1 in the code is an indicator of the relevance of Windows 7. It is not.

Windows 7 is a significant and evolutionary advancement of the client operating system. It is in every way a major effort in design, engineering and innovation. The only thing to read into the code versioning is that we are absolutely committed to making sure application compatibility is optimized for our customers.

We're just over a week away from showing off Windows 7 at PDC and WinHEC. I look forward to sharing more soon!

Introducing Windows 7

Mike Nash — Mon, 13 Oct 2008 22:56:00 GMT

Hi there, Mike Nash here.

For me, one of the most exciting times in the release of a new product is right before we show it to the world for the first time. And that time is right now.

In a few weeks we are going to be talking about the details of this release at the PDC and at WinHEC. We will be sharing a pre-beta "developer only release" with attendees of both shows and giving them the first broad in-depth look at what we've been up to. I can't wait for them to see it.

And, as you probably know, since we began development of the next version of the Windows client operating system we have been referring to it by a codename, "Windows 7." But now is a good time to announce that we've decided to officially call the next version of Windows, "Windows 7."

While I know there have been a few cases at Microsoft when the codename of a product was used for the final release, I am pretty sure that this is a first for Windows. You might wonder about the decision.

The decision to use the name Windows 7 is about simplicity. Over the years, we have taken different approaches to naming Windows. We've used version numbers like Windows 3.11, or dates like Windows 98, or "aspirational" monikers like Windows XP or Windows Vista. And since we do not ship new versions of Windows every year, using a date did not make sense. Likewise, coming up with an all-new "aspirational" name does not do justice to what we are trying to achieve, which is to stay firmly rooted in our aspirations for Windows Vista, while evolving and refining the substantial investments in platform technology in Windows Vista into the next generation of Windows.

Simply put, this is the seventh release of Windows, so therefore "Windows 7" just makes sense.

We are very excited about the opportunity to tell you more about Windows 7 in the coming weeks, and show you how we have continued to build on investments begun in Windows Vista to deliver on the next release of the Windows operating system.

I look forward to sharing more with you in the coming weeks and months.

Chris Flores — Wed, 24 Sep 2008 23:19:00 GMT

While this blog is committed to bringing you the latest info on Windows Vista, I wanted to take a moment to take a look at what everyone's been talking about today: PDC, WinHEC and Windows 7.

The Professional Developer Conference (PDC) , taking place in Los Angeles Oct. 27th - 30th, is an event designed for leading-edge developers and software architects that are interested in the future of the Microsoft platform. If you're responsible for the technical strategy in your organization, or you're a highly skilled developer who likes to delve deep into the heart of the platform, then PDC is for you! You can register today for PDC by heading over to http://www.microsoftpdc.com/. Hurry, spots are filling fast!

The Windows Hardware Engineering Conference (WinHEC), taking place in Los Angeles Nov. 5th - 7th, focuses on designing PCs, servers, and devices that run and interface with Microsoft Windows with a focus on Windows 7. WinHEC brings together engineers, developers and testers, and product planners giving them a opportunity to stay aligned with Microsoft technology roadmaps and new product opportunities. To register for WinHEC - click here (register before Oct. 3rd and save $400!).

At each event you will hear from lead Windows Engineers including Steven Sinofsky, as well as see firsthand the next Windows OS. Just announced today - at both shows we will handing out a pre-beta build of Windows 7. By attending these events, you will be one of a select few to receive a pre-beta build of Windows 7 to take with you. If that's not incentive to head to these events, I don't know what is ;-)

Microsoft demonstrates Multi-touch

Chris Flores — Wed, 28 May 2008 03:21:00 GMT

For years Microsoft has been investing in many forms of natural input in order to simplify the way people interact with their PC's and devices. The advent of the original Windows graphical user interface forever changed the way people used their PC's. Today, advances in pen and handwriting technology in Windows Vista offers students a natural and intuitive way to capture searchable notes and diagrams in the classroom. Others are using this technology to quietly capture pen based notes during meetings. Speech recognition, something which was once considered science fiction, is enabling many Windows Vista users to see, hear, and use their computers for the very first time.

Last year, at the Wall Street Journal's D: All Things Digital conference, Bill Gates introduced a groundbreaking new computing experience called Surface. Surface harnesses touch and multi-touch capabilities to provide users with a natural way to interact directly with computing devices. Expect to see the table-like Surface devices in hotels, retail establishments, restaurants and public entertainment venues.

Touch is quickly becoming a common way of directly interacting with software and devices. Touch-enabled surfaces are popping up everywhere including laptop touch pads, cell phones, remote controls, GPS devices, and more. What becomes even more compelling is when this experience is delivered to the PC -on a wide variety of Windows notebooks, in all-in-one PC's, as well as in external monitors. In working with our broad ecosystem of hardware and software manufactures, we're excited to be showing some of the great work and investments we are working on in Windows 7.

Tonight, at this year's D:All Things Digital conference, Julie Larson-Green showed Walt Mossberg how a few of the multi-touch innovations first previewed in Surface will ultimately enhance the next version of Windows. A transcript of the demo can be found here: http://d6.allthingsd.com/20080527/gates_ballmer/.

Below is an abridged version of the demo that Julie delivered this evening. Please note, the applications you will see are for demonstration purposes only...but it's all Windows 7 underneath.

Communicating Windows 7

Chris Flores — Tue, 27 May 2008 12:09:00 GMT

Typically when Microsoft ships a new OS (like Windows Vista), we immediately start talking about the next version-which begs two questions: 1) is Microsoft working on a new version of Windows, and if so, 2) why aren't you talking about it?

I thought I would spend a minute giving you an update on where we are. First, yes, we are working on a new version of Windows. As you likely know, it's called Windows 7.We are always looking for new ways to deliver great experiences for our customers. This is especially true of Windows - where we're constantly examining trends in hardware, software and services to ensure that we continue to drive the innovation that has both made Windows the world's most popular operating system and has provided a foundation on which our partners built great products and businesses. When we shipped Windows 2000, we were already working on Windows XP and we started working on Windows Vista even before we released Windows XP. So naturally, we've been thinking about the investments we made in Windows Vista and how we can build on these for the next version of Windows.

What is a little different today is when and how we are talking about the next version of Windows. So, why the change in approach? We know that when we talk about our plans for the next release of Windows, people take action. As a result, we can significantly impact our partners and our customers if we broadly share information that later changes. With Windows 7, we're trying to more carefully plan how we share information with our customers and partners. This means sharing the right level of information at the right time depending on the needs of the audience. For instance, several months ago we began privately sharing our preliminary plans for Windows 7 with software and hardware partners who build on the Windows platform. This gave them an opportunity to give us feedback and gave us the opportunity to incorporate their input into our plans. As the product becomes more complete, we will have the opportunity to share our plans more broadly. Steven Sinofsky, Windows and Windows Live Engineering SVP, talks more about this in his interview with CNET's Ina Fried, published today: http://news.cnet.com/8301-13860_3-9951638-56.html.

We know that this is a change in our approach, but we are confident that it will help us not only to build even better products, but also to be more predictable in the delivery of our products. We also know that this change has led to some confusion, so we would like to share information today that will hopefully clear up some of this.

Before we talk about what's ahead, we should take a look at where we are today with Windows Vista. From a quality perspective, both Windows Vista SP1 and the ecosystem have delivered measurable progress in the six dimensions of quality we track -- device compatibility, application compatibility, reliability, performance, battery life and security. The business results speak for themselves. As of March 31, we had sold more than 140 million Windows Vista licenses, and analyst firm forecasts indicate that Windows Vista adoption among businesses is on a similar pace as Windows XP in similar timeframes. Millions of enterprise users are already running Windows Vista, and we invite you to read their stories published in more than 100 case studies. The benefits they are experiencing range from energy conservation, lower TCO for mobile users, and greater security. Our job is not done, but we've worked hard with our ecosystem to improve the quality of Windows Vista and we're pleased with the customer response.

Another question we often get asked is whether Windows 7 is a major release. The answer is "yes" -- it's hard to describe any product that is used by millions of people and worked on by thousands of engineers as anything else. That said, the long-term architectural investments we introduced in Windows Vista and then refined for Windows Vista SP1 and Windows Server 2008 will carry forward in Windows 7. Windows Vista established a very solid foundation, particularly on subsystems such as graphics, audio, and storage. Windows Server 2008 was built on that foundation and Windows 7 will be as well. Contrary to some speculation, Microsoft is not creating a new kernel for Windows 7. Rather, we are refining the kernel architecture and componentization model introduced in Windows Vista. While these changes will increase our engineering agility, they will not impact the user experience or reduce application or hardware compatibility. In fact, one of our design goals for Windows 7 is that it will run on the recommended hardware we specified for Windows Vista and that the applications and devices that work with Windows Vista will be compatible with Windows 7.

We are well into the development process of Windows 7, and we're happy to report that we're still on track to ship approximately three years after the general availability of Windows Vista. As always, we will be releasing early builds of Windows 7 prior to its general availability as a means to gain feedback, but we're not yet ready to discuss timing and specific plans for any Beta releases. In the meantime, customers can confidently continue with their Windows Vista deployment plans.
