The Technical Side Of Windows 8
As we mentioned in the opening of this article, the single biggest addition to Windows 8 coming from Windows 7 will be Metro. Microsoft’s last major overhaul of Windows’ underpinnings was Windows Vista, and like Windows 7 before it, Microsoft is not looking to significantly alter the operation of the Windows kernel or related systems for Windows 8. With that said this doesn’t mean that there aren’t any technical changes that will ship with Windows 8.
Fundamentally Microsoft wants to keep the system requirements for Windows 8 the same as Windows 7, which means it needs to run (with varying definitions of “smoothly”) on a 1GHz CPU paired with 1GB of RAM and a DX9 class GPU. Realistically as their published requirements stand there is one difference from Windows 7: Windows Display Driver Model (WDDM). Windows 7 would work with older XPDM drivers (albeit without any of the benefits of WDDM), however Windows 8 specifically mentions WDDM as a requirement. This makes sense given the greater reliance on the GPU for Metro, but it also means there are going to be some machines out there using very early DX9 GPUs (e.g. Intel GMA 900) that won’t be able to run Windows 8 due to a lack of video drivers.
In any case the addition of ARM into the mix will be sure to spice things up., While Microsoft is optimizing Windows 8 to run on ARM CPUs there’s a vast range of ARM CPUs, and this is the full version of Windows. Microsoft’s current system requirements are easily discernable as x86 based, and we’d expect the ARM requirements to be fairly high to keep pace. Give the launch of quad core ARM SoCs later this year, it’s likely that will be a popular pairing with Windows 8 when it launches.
On a final note about system requirements, while Microsoft isn’t talking about specific versions of Windows 8 at this time, they’ve made it clear that x86 will live on for at least one more generation in order to fulfill their desire to have Windows 8 run on everything Windows 7 ran on. So x86 versions of Windows should be expected.
Moving on, as this was a press session as opposed to a technical session, Microsoft was a bit light on the details. We’re expecting quite a bit more in the next couple of days, but for the moment we’ve only been briefed on a few user-facing technologies that are new to Windows 8.
On the hardcore side of things, Microsoft has added a few tricks to Windows in order to keep memory usage from growing and to make the OS better suited for tablets. On the memory side they have added Page Combining, which will combine duplicate memory pages into a single page. This is primarily to reduce the overhead from multiple applications all having copies of the same shared resource by having applications outright share that resource’s memory pages. Page Combining will primarily be a tool for reclaiming memory when memory usage is approaching critical levels.
For making the OS better suited for tablet hardware, Microsoft has focused on small changes that can help the hardware sleep longer and wake up less often. Coalescing system timers and a dynamic tick mechanism are two such features that will be coming to Windows 8 (unfortunately we don’t have any more details on their function at this time). Meanwhile Metro will play a big part in making Windows tablet friendly, as Metro applications will be designed from the start to be able to handle phone/tablet style process management. This is to say that discarded applications will continue to stay open as a background application, having all of their memory pages intact but unable to schedule CPU time so long as they’re a background application. They’ll remain in this state until the OS decides to evict them, at which point they need to be able to gracefully shut down and resume when the user re-launches the application. Internally Microsoft calls this freezing and rehydrating an application.

"Microsoft would like developers writing applications in runtime or interpreted languages such as C#, VB, HTML5/CSS/JavaScript, and even Silverlight"Silverlight is not a language, its essentially just .NET for WP7 (and confusingly for web applications) its language is c#.
Also, I think the author needs to look up WPF, this technology is already a complete replacement for the old style win32/winforms development. I imagine the new technologies will be related to WPF.

very original, very ugly. never saw such a bad user .not all people use tablet ms.damianrobertjones - Tuesday, September 13, 2011 - link
Very easy to use, attractive to the non-techies, nearly everyone will eventually use a tablet.robinthakur - Wednesday, September 14, 2011 - link
Is it attractive though? It looks like a very festive powerpoint presentation...The main reasons that people stick with Windows, against all odds, is compatibility and familiarity. This blows away the latter. You saw how well they all took to Windows 7 Phone. Besides which, tere is always the danger that companies will skip Windows 8 en masse as they did with Vista, and that will almost force MS to reduce the amount of influence and interaction afforded to Metro in Windows 9/10.iwodo - Tuesday, September 13, 2011 - link
I like Metro as a concept, or idea. But i have problem with Microsoft's implementation of Metro. It is, very Linux like. Apart from the Color i can tell it is from M$, almost all things else are like KDE / Gnome.Ribbon is a mess. Yes it exposes Far more options to the users. Yes it places the statistically most used function on top. Yes it is, may be easier to use.
But I am sorry. It is ugly.
I just wish, Microsoft could have a single switch that will make Windows 8 and Office 2010 all in collapsed mode Automatically.

"single switch that will make Windows 8 and Office 2010 all in collapsed mode Automatically."This already exists in Windows 7 and Office 2010. It's been around for years. You can minimize the ribbon in two easy ways.
1) Double click the top of the ribbon
2) Right click the top of the ribbon, select 'Minimize the Ribbon"
Hope this helps,
Mark

I really don't have anything against Metro, and I think Microsoft have to do something drastic to the Windows UI to make it scale from desktops to tablets. And Metro could be it.However my problem is that if its currently half and half (like you mention the other settings loads normal control panel) then I don't think that's an going to be a good UIX, in fact I think it'll be damn jarring and piss people of more than it should.
The OS, and control thereof needs to be fully Metro'ised, (or at least fit seamlessly in, it doesn't look like Vista/Win7 borders on task manager or explorer really fit).
Basically if MS don't do that, say for control panel, they are basically admitting Metro isn't a comprehensive enough UI design.
If MS state at some point, yes Win8 is half and half, and Win9 will complete the transition then fine, its the same place Apple is in with Lion I think (transitioning from an open desktop to a locked device)

The Control Panel has a Metro UI (you can see it several times in the demo). In fact, unless you need to open a specific app or do file management, you never have to see the desktop if you don't want to. And with the way apps are setup, I doubt you'll really care where the file is stored, as long as you're able to access it through search and it's backed up safely.Will the desktop disappear? No. But for a good chunk of what people use their computers for (e-mail and web surfing), it's not really that important. And getting away from traditional file management will be a BIG step forward to the future.

I can't wait to load the beta release whenever it comes out. Looks very intriguing from just glancing at it.Would love to start playing with this OS.

and not succeeding.For a smart phone or tablet I can see the point although looks clunky to me.
For a desktop just awful.
The concept of yet more "ribbons" appearing is even worse. MS idea of context (especially in Word) is clearly not related to any work I or anyone I know does. Mind you I still think that Word is a much worse word processor for proper business than Wordperfect 5.1 which is only 20 years old
