Windows 7’s user interface overhaul, there’s is a lot of hype about this right now. We know what’s going to change, we know what it looks like, but there’s one important question that has not really been given much stage time: why? At PDC, one session was dedicated to just that question. Speaking was Chaitanya Sareen, part of the windows user interface team. He placed the changes in Windows 7 into context, talked about Windows’ user interface history, and explained why certain changes were made. An interesting insight into the goals of the Windows 7 interface.

Microsoft has been hinting that even though it had no plans to make major changes to the Windows kernel, it did have a scheme up its sleeve to make Windows 7 and Windows 7 Server better suited to working on multicore/parallel systems. Now details are becoming clearer as to how Microsoft plans to do this.

During the debut of the pre-beta of Windows 7 this week, Windows Engineering Chief Steven Sinofsky made a passing reference to Windows 7 being able to scale to 256 processors. But he never said how this would be enabled.

Mark Russinovich, Technical Fellow in Microsoft’s Core OS division, explained in more detail how Microsoft has managed to do this in a video interview published on Microsoft’s Channel 9 Web site. Russinovich said that Microsoft has managed to break the dispatcher lock in Windows — a task that had stumped even the father of the Windows NT operating system, David Cutler. When Cutler designed Windows for the server, systems beyond 32-way seemed far, far away, Russinovich said.

Presented below is video of Mark Russinovich (of sysinternals fame… ya seriously the guy is a geek hero) enlightens us on the new kernel constructs in Windows 7. One very important change in Windows 7 kernel is the dismantling of the Dispatcher Spin Lock and redesign and implementation of its functionality into separate components.

Windows 7 pre-beta hits BitTorrent. What you’ll find is the pre-beta version of Microsoft’s Windows 7 operating system released to developers at the Professional Developers Conference. Note that this isn’t the latest “beta” build who’s screenshots are making the rounds (the one with the new taskbar, etc) but you can find it in 32-bit and 64-bit versions out there on the net. At the time of this writing Windows 7 Build 6801 seems to be the latest available.

Comments seem to indicate that it runs well in VMWare and is working for most people. If you wanna take a gander and don’t mind running “unreleased”, pre-beta code then you can find it on bittorrent by looking on BTJunkie.

“Oh lord, not another Vista article!” Like me, I’m sure many of you might be thinking something along those lines whenever you see an article with the word ‘Vista’ in the title these days. We’ve had what can only be described as a plethora of articles on Windows Vista, almost all of them repetitive, one-sided and of little practical use. Some of them have bordered on the absurd, such as Infoworld declaring Windows Vista to be the second biggest tech blunder in history, giving as its reason a one paragraph description that serves more to highlight the author’s ignorance than provide any actual logic for their decision. We’ve been suffering under the weight of these nonsensical, sensationalist and opinion-laded pro- and anti-Vista articles for far too long.

So what makes this Vista article any different? The title provides a clue: it’s as much about providing practical working solutions to resolve some of the commonly-quoted Vista annoyances as anything else. That in itself should give all Vista users a reason to read it. However it doesn’t matter whether you use Vista or not, because this article does something that most of the others don’t: it takes an objective and up-to-date look at the current state of Vista, with a range of facts, clear examples and informed opinions aimed squarely at debunking a lot of the myths and FUD we’ve been gagging on for the past year. So for those of you still considering whether to make the switch from XP, for those of you who want to abandon Vista and go back to XP, for those of you who used Vista a while ago and who are wondering whether it’s worth using again now - this article puts things in perspective with the latest facts.

What this article doesn’t do: it doesn’t try to make you believe that Vista is the greatest (or worst) thing since sliced bread. It doesn’t try to force you to think a certain way by taking liberties with the truth just to prove a point. It doesn’t try to highlight how witty and incisively sarcastic I can be. And most certainly this article doesn’t try to dazzle you with technical jargon.
