Windows 7 (formerly known as Blackcomb and Vienna) is the working name for the next major version of Microsoft Windows as the successor to Windows Vista.[4] Microsoft has announced that it is "scoping Windows 7 development to a three-year timeframe", and that "the specific release date will ultimately be determined by meeting the quality bar."[5] Windows 7 is expected to be released by 2009 or near January 2010.[2] The client versions of Windows 7 will ship in both 32-bit and 64-bit versions.[5] A server variant, codenamed Windows Server 7, is also under development.

Microsoft is maintaining a policy of silence concerning discussion of plans and aspirations for Windows 7 as it focuses on the release and marketing of Windows Vista,[6] though some early details of various core operating system features have emerged. As a result, little is known about the feature set, though public presentations from company officials have disseminated information about some features. Leaked information from people to whom Milestone 1 (M1) of Windows 7 was shipped also provides some insight into the feature set.

Development

History

In about 2000 Microsoft started the planning to follow up Windows XP and its server counterpart Windows Server 2003 (both codenamed Whistler) with a major new release of Windows that was codenamed Blackcomb (both codenames refer to the Whistler-Blackcomb resort). This new version was at that time scheduled for a 2005 release. [7] [8]

Major features were planned for Blackcomb, including an emphasis on searching and querying data and an advanced storage system named WinFS to enable such scenarios. In this context, a feature mentioned by Microsoft co-founder Bill Gates for Blackcomb was "a pervasive typing line that will recognize the sentence that [the user is] typing in."[9]

Later Blackcomb was delayed and an interim minor release, codenamed "Longhorn", was announced for a 2003 release.[10] By the middle of 2003, however, Longhorn had acquired some of the features originally intended for Blackcomb, including WinFS, the Desktop Window Manager, and new versions of system components built on the .NET Framework. After the 2003 "Summer of Worms", where three major viruses − Blaster, Sobig, and Welchia − exploited flaws in Windows operating systems within a short time period, Microsoft changed its development priorities, putting some of Longhorn's major development work on hold in order to develop new service packs for Windows XP and Windows Server 2003 that included a number of new security and safety features. Development of Longhorn was also "reset" in September 2004 (see Mid-2004 to Mid-2005: Development "reset") as a result of concerns about the quality of code that was being introduced to the operating system. The eventual result of this was that WinFS, the Next Generation Secure Computing Base, and other features seen in Longhorn builds were deemed "not ready" for wide release, and as such did not appear in Longhorn, when it was released as Windows Vista and Windows Server 2008.

As major feature work on Windows Vista wound down in early 2006, Blackcomb was renamed Vienna.[11] However, following the release of Windows Vista, it was confirmed by Microsoft on July 20, 2007 that "the internal name for the next version of the Windows Client OS"[5] is Windows 7, a name that had been reported by some sources months before.[11]

Focus

Microsoft's Ben Fathi claimed on February 9 2007 that the focus on the operating system was still being worked out, and could merely hint at some possibilities:[12]

We're going to look at a fundamental piece of enabling technology. Maybe it's hypervisors. I don't know what it is" [...] "Maybe it's a new user interface paradigm for consumers.

Bill Gates, in an interview with Newsweek, suggested that the next version of Windows would "be more user-centric."[13] When asked to clarify what he meant, Gates said:

That means that right now when you move from one PC to another, you've got to install apps on each one, do upgrades on each one. Moving information between them is very painful. We can use Live Services to know what you're interested in. So even if you drop by a [public] kiosk or somebody else's PC, we can bring down your home page, your files, your fonts, your favorites and those things. So that's kind of the user-centric thing that Live Services can enable. [Also,] in Vista, things got a lot better with [digital] ink and speech, but by the next release there will be a much bigger bet. Students won't need textbooks; they can just use these tablet devices. Parallel computing is pretty important for the next release. We'll make it so that a lot of the high-level graphics will be just built into the operating system. So we've got a pretty good outline.

Later, Gates also said that Windows 7 will also focus on performance improvements:[14]

We're hard at work, I would say, on the next version, which we call Windows 7. I'm very excited about the work being done there. The ability to be lower power, take less memory, be more efficient, and have lots more connections up to the mobile phone, so those scenarios connect up well to make it a great platform for the best gaming that can be done, to connect up to the thing being done out on the Internet, so that, for example, if you have two personal computers, that your files automatically are synchronized between them, and so you don't have a lot of work to move that data back and forth.

Bill Veghte stated that Windows 7 will not have the kind of compatibility issues with Vista that Vista has with previous versions:[15]

You've let us know you don't want to face the kinds of incompatibility challenges with the next version of Windows you might have experienced early with Windows Vista. As a result, our approach with Windows 7 is to build off the same core architecture as Windows Vista so the investments you and our partners have made in Windows Vista will continue to pay off with Windows 7. Our goal is to ensure the migration process from Windows Vista to Windows 7 is straightforward.

Milestone 1

The first known build of Windows 7 was identified as a "Milestone 1 (M1) code drop" according to TG Daily with a version number of 6.1.6519.1. It was sent to key Microsoft partners by January 2008 in both x86 and x86-64 versions.[16][17] Though not yet commented on by Microsoft, reviews and screenshots have been published by various sources.[18][19]The M1 code drop installation comes as either a standalone install or one which requires Windows Vista with Service Pack 1, and creates a dual-boot system.[20]

On April 20, 2008, screenshots and videos of a second build of M1 were leaked with a version number of 6.1.6574.1. This build included changes to Windows Explorer as well as a new Windows Health Center.[21]

A standalone copy of build 6519 was leaked initially to private FTPs by BETAArchive on June 10, 2008, which quickly spread to many torrent trackers.[22]

Later builds

According to TG Daily article of January 16, 2008, the Milestone 2 (M2) code drop was at that time scheduled for April or May of 2008.[16] User interface appearance changes are expected to appear in later builds of Windows 7.[23]

Milestone 3 (M3) is listed as coming in the third quarter[16] and although the release dates of beta versions and release candidates are currently "to be determined" the release to manufacturing of Windows 7 has been alternately confirmed for the second half of 2009[24] or the first half of 2010[2] depending on who was speaking at the time.

Bill Gates commented in a press conference in April 2008 that a new version [of Windows] would come "in the next year or so".[25] According to additional clarification by Microsoft, he was only referring to availability of alpha or beta versions of Windows 7.[26]

Unveiling

The Windows 7 user interface was demonstrated for the first time at the D6 conference[27] during which Steve Ballmer acknowledged a projected release date of late 2009.[28] The build of Windows 7 that was on display had a different taskbar than found in Windows Vista, with, among other features, sections divided into different colors. The host declined to comment on it, stating "I'm not supposed to talk about it now today".[29]

Features

Windows 7 has reached the Milestone 1 (M1) stage and has been made available to key partners.[16] According to reports sent to TG Daily, the build adds support for systems using multiple heterogeneous graphics cards and a new version of Windows Media Center.[16] New features in Milestone 1 also reportedly include Gadgets being integrated into Windows Explorer, a Gadget for Windows Media Center, the ability to visually pin and unpin items from the Start Menu and Recycle Bin, improved media features, the XPS Essentials Pack being integrated, and a multiline Calculator featuring Programmer and Statistics modes along with unit conversion.

Reports indicate that a feedback tool included in Milestone 1 lists some coming features: the ability to store Internet Explorer settings on a Windows Live account, updated versions of Paint and WordPad, and a 10 minute install process.[30] In addition, improved network connection tools might be included.

In build 6574, the Windows Security Center has been renamed the Windows Health Center, and focuses on monitoring the complete health status of the computer in a central location.

In the demonstration of Windows 7 at D6, the operating system featured multi-touch, including a virtual piano program, a mapping and directions program and a touch-aware version of Paint.

MinWin

A minimalistic variation of the Windows API and core libraries, known as MinWin, was developed as part of the Windows 7 architecture. The MinWin development efforts were aimed towards componentizing the Windows libraries and reducing their dependencies, with a view to carving out the minimal set of components required to build a self-contained system.[31] MinWin takes up about 25 MB on disk and has a working set (memory usage) of 40 MB.[32] It lacks a graphical user interface and is interfaced using a full-screen command line interface.[33][32] It includes the I/O and networking subsystems.[31][33] MinWin was first publicly demonstrated on October 13, 2007 by Eric Traut. The demo system included an OS image, made up of about 100 files, on which a basic HTTP server was running.[32][34]

Incidentally, the name MinWin was also used earlier to refer to what is currently known as Server Core in Windows Server 2008.[31][33] Both efforts are intended to consolidate and modularize the core of Windows; however, the two are quite different in implementation. With Server Core, the functionality of the OS is constrained according to server roles, and unneeded components (which will never be used as the role isn't supported) are removed from the binary image. However, the dependencies still exist in code, and the code cannot compile without the components. In contrast, with MinWin, the dependencies are consolidated into MinWin and what is not needed is removed at the code level itself. As a result, the code compiles even without any extraneous components and builds a stripped-down self-contained OS kernel image.[33][31]

In an interview with Ina Fried of Cnet's News.com, Steven Sinofsky described the Windows 7 kernel as a further evolution of the Windows Server 2008 kernel, itself an evolution of the Windows Vista kernel.[35]

Methods of input

On December 11, 2007, Hilton Locke, who worked on the Tablet PC team at Microsoft reported that Windows 7 will have new touch features. An overview of the touch capabilities was demonstrated at the All Things Digital Conference on May 27, 2008. A video demonstrating the multi-touch capabilities was later made available on the web on the same day.[36]

Also, Bill Gates has said that Windows 7 is also "a big step forward" for speech technology and handwriting recognition.[37]

Virtual hard disk

On May 21, 2008, Microsoft posted a job opening for Windows 7 regarding work to implement VHD support, i.e. support for single-file containers that represent an entire hard drive including partitions, and transparently performing I/O operations on this as a typical hard drive, including boot support. [38]

In Windows 7, our team will be responsible for creating, mounting, performing I/O on, and dismounting VHDs (virtual hard disks) natively. Imagine being able to mount a VHD on any Windows machine, do some offline servicing and then boot from that same VHD. Or perhaps, taking an existing VHD you currently use within Virtual Server and boost performance by booting natively from it.

Antitrust regulatory attention

The development of Windows 7 has already attracted the attention of the antitrust regulators who oversee Microsoft's operations following the 2001 United States Microsoft antitrust case settlement. According to status reports filed, the three-member panel began assessing the prototypes of the new operating system in February 2008.[39]

Michael Gartenberg, an analyst at Jupiter Research said that, "[Microsoft's] challenge for Windows 7 will be how can they continue to add features that consumers will want that also don't run afoul of regulators."[39]
