Windows 7 (formerly codenamed Blackcomb, then Vienna) is a future version of Microsoft Windows. It is expected to be the successor to Windows Vista. Microsoft has confirmed that the planned development time frame is at least three years, putting the release date around 2010[1]. On July 20, 2007, Microsoft confirmed that Windows 7 is "the internal name for the next version of the Windows Client OS".[1] Microsoft has refrained from discussing the details about Windows 7 publicly as they focus on the release and marketing of Windows Vista,[2] though some early details of various core operating system features have emerged.

History
The codename Blackcomb was originally assigned to a version of Windows that was planned to follow Whistler (the codename for Windows XP and Windows Server 2003, which together with Blackcomb were codenamed after the Whistler-Blackcomb resort). A feature mentioned by Bill Gates for Blackcomb was "a pervasive typing line that will recognize the sentence that [the user is] typing in."[3] In late 2001 the release of Blackcomb was being scheduled for 2005 and in August it was announced that a minor intermediate release, codenamed Longhorn (after a bar in the Whistler-Blackcomb Resort), would ship before Blackcomb. Over the following years Longhorn morphed in fits, starts, and delays to incorporate many of the features promised for Blackcomb. In early 2006, Blackcomb's codename was changed to Vienna and was later changed to Windows 7.[4][5]
Editions
While it was originally not specified if Blackcomb would be a client or server release, Microsoft later clarified that Blackcomb would still be the successor to Windows Server 2003, when asked if there would be a server version of Longhorn. However, Microsoft later did create a server version of Longhorn. Microsoft has stated that Windows 7 is the working name for the next client version of Windows, but has made no explicit mention of a server version by the name Windows 7.
Focus
On February 9 2007, Microsoft's Ben Fathi claimed that the focus on the operating system was still being worked out, and could merely hint at some possibilities:[4]
| “ | 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, also suggested that the next version of Windows would "be more user-centric."[6] 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. | ” |
Features
Microsoft is maintaining a policy of silence concerning plans and aspirations for Windows 7. As a result, very little is known about the feature set. However, from interviews and speeches of company executives certain features have been known.[6]
MinWin
A minimalistic variation of the Windows kernel, known as MinWin, is being developed for use in Windows 7. The MinWin development efforts are aimed towards componentizing the Windows kernel and reducing the dependencies with a view to carving out the minimal set of components that is required to build a self-contained kernel as well as reducing the disk footprint and memory usage.[7] MinWin takes up about 25 MB on disk and has a working set (memory usage) of 40 MB.[8] It lacks a graphical user interface and is interfaced using a full-screen command line interface.[9][8] It includes the I/O and networking subsystems.[7][9] MinWin was first 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.[8][10] Incidentally, the name MinWin was also used earlier to refer to what is currently known as Server Core in Windows Server 2008.[7][9] However, the two are quite different. While both efforts are to consolidate and componentize the core of Windows, 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.[9][7]
Touch features
On December 11 2007, Hilton Locke, who worked on the Tablet PC team at Microsoft reported that Windows 7 will have new touch features.
| “ |
I will say that if you are impressed by the "touch features" in the iPhone, you'll be blown away by what's coming in Windows 7. Now if only we could convince more OEMs that Windows Touch Technology is going to drive their sales.[11] |

Availability
The client versions of Windows 7 will ship in both 32-bit and 64-bit versions.[1] Server versions of Windows 7, however, will be exclusively 64-bit.[12]
