Poking around the registry of Windows 8 Consumer Preview, Windows8Beta discovered the operating system, at least the PC version, as having six variants. There are also mentions of ARM variants (for ARM tablets and notebooks), but let's look at the PC SKUs:

• Windows 8 Starter Edition, for low-cost PCs, netbooks, nettops, etc., probably targeting emerging markets only
• Windows 8 Home Basic, for value desktop PCs, netbooks, and notebooks
• Windows 8 Home Premium, for mainstream desktops and notebooks
• Windows 8 Professional, for home, office desktops and more functional notebooks
• Windows 8 Professional Plus, for office desktops and notebooks in dense local networks, probably has extra management, data security features
• Windows 8 Ultimate Edition, has the complete feature-set of the OS

The new SAPPHIRE HD 7800 series of graphics cards is based on the third family of GPU's from AMD built in its new 28nm process and featuring the highly acclaimed GCN graphics processing architecture. The new HD 7870 and HD 7850 GPUs have an optimised internal structure sharing many of the features of the high performance HD 7900 series already released but with fewer Stream processors and a new high speed 256-bit memory interface to the latest DDR5 memory types. It is aimed at mainstream gamers looking for excellent performance together with good value and all the latest features.

Two models of the HD 7870 are being introduced by SAPPHIRE at launch. The first is the SAPPHIRE HD 7870 which will ship with a core clock speed of 1GHz, and will be known as the SAPPHIRE HD 7870 GHz Edition. It is equipped with 2GB of the latest DDR5 memory clocked at 1200MHz (4.8Gb/s effective). At the same time SAPPHIRE is introducing a higher performance model, the SAPPHIRE HD 7870 GHz OC Edition, in which both core and memory are factory overclocked and the PowerTune limits are raised to allow even further performance tuning. Both models are equipped with SAPPHIRE's new dual-extractor technology - Dual-X - a highly efficient multi-heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load.

Microsoft's Windows 8 is reported to come with a "killswitch", which can by flipped by Microsoft to delete malware downloaded from its App Store by unsuspecting customers. Last year, Google's Android Marketplace was swarmed by malware disguised as popular applications from various other publishers. These applications were bought and downloaded by unsuspecting users. When word reached Google, it flipped a killswitch with Android that instantly removed these bogus applications across thousands of devices. It's not just Google, Apple too has a similar killswitch with which it keeps its App Store users safe from malware.

News of killswitches with Windows (in-turn the PC platform), isn't going in too well with advocates of privacy and free-speech, who fear that Microsoft's planted killswitch gives it unwarranted power to remotely erase applications and user data (connected to these applications), without the consent of the user. It could then be used as a potential censorship tool, or even an anti-competition tool, by synthetically-engineering market-shares of software used by people.

With Windows 8, Microsoft is integrating an eXtensible Host Controller Interface (xHCI) driver, which serves as a common driver for USB 3.0 host controllers. Expreview put this driver to test with a Renesas USB 3.0 controller, and compared its performance to when the controller is backed by Renesas' own driver (ver. 2.1.28.0). The controller is a μD720200F1 found on ASUS P8P67 Deluxe motherboard. The reviewer used Orico UE3 16GB USB 3.0 flash drive that uses SLC NAND flash memory.

The flash was put through four synthetic tests on a constant hardware setup, differences in performance were attributed to the drivers. Tests included HDTune, ATTO, AS SSD, and CrystalDiskMark. The xHCI driver provided by Microsoft trailed a tiny/insignificant notch behind the third-party driver provided by Renesas. In HDTune, the performance graph was smoother (fewer variations) with the Microsoft xHCI driver. In sequential speed tests, variation between the two drivers seldom exceeded 2%. The xHCI driver will ship with Windows 8, letting you run USB 3.0 host controllers and compatible devices right out of installation. The drivers pass through Microsoft's WHQL, although the update cycle of drivers provided by Microsoft is traditionally known to be slower, in some cases they have found to be more stable. Screenshots with "MS" markings (below) show results for the xHCI driver.More results follow.

AMD posted a new Catalyst driver (8.93.7 RC10) specifically for Windows 8 Consumer Preview. The driver is WDDM 1.2 compliant, and supports all launched AMD Radeon GPUs from HD 5000 thru HD 7000 series (except HD 7900 and HD 7700); AMD A-Series, C-Series, and E-Series APUs; FirePro, and FirePro 3D series products. Highlights include:

• Native Stereo 3D support: Windows 8 will natively support Stereo 3D for full-screen and windowed gaming, and video applications
• Unified Video API - Video playback is now integrated within the DirectX 11 API; enabling simultaneous high quality Video and 3D content, and the potential for enhanced video transcoding performance
• Optimized screen rotation
• Improved sleep / resume performance
• Optimized Power Consumption

NVIDIA confirmed today that it is working with Microsoft on a program to distribute Windows 8 test PCs to software developers and device manufacturers powered by the Tegra 3 quad-core mobile processor with 4-Plus-1 architecture.

This seeding program enables these parties to create a rich ecosystem of apps and devices for Windows 8 on ARM-based processors.

Qualcomm Incorporated today announced that its Snapdragon processor will be joining Microsoft Corp.'s Windows on ARM developer seeding program. Qualcomm is working with Microsoft to provide test PCs to select developers in order to test and optimize apps for forthcoming Snapdragon-powered Windows on ARM PCs and tablets. This invitation-only program will combine a pre-release version of Windows on ARM with next-generation, high performance Snapdragon S4 test PCs. These test PCs are not representative of commercial form factors or the final Windows on ARM experience; they are designed to give developers early access to building and testing Windows Metro style apps on Qualcomm's latest technology.

The Windows on ARM developer seeding program will help ensure that Windows Metro style apps available in the Windows Store work great on all Windows 8-based PCs, including those with Qualcomm's ARM-compliant Snapdragon processors.

Microsoft Corp. today announced the availability of the Windows 8 Consumer Preview - the next milestone of the Windows operating system. This latest preview will be made available for download starting today at preview.windows.com. The Windows 8 Consumer Preview offers a more robust experience for testing the world's most popular operating system and is available to the widest range of people yet following the initial release of the Windows 8 Developer Preview late last year. The Developer Preview received more than 3 million downloads.

"With Windows 8, we reimagined the different ways people interact with their PC and how to make everything feel like a natural extension of the device, whether using a Windows 8 tablet, laptop or all-in-one," said Steven Sinofsky, president of the Windows and Windows Live Division at Microsoft. "The Windows 8 Consumer Preview brings a no-compromises approach to using your PC."

Even as there's quite some buzz around Microsoft's next major version of Windows, there are reports such as one from Bright Side of News citing "multiple sources close to Microsoft, or inside [it]," revealing the tentative launch schedule of the two main branches of Windows: for x86 platforms (client and enterprise), and ARM (for tablets and compact computing devices). Windows 8 for clients and enterprise (x86 architecture), will get up to 5 months' head-start over the much hyped ARM version for tablets. It is expected to be launched some time in Q4 2012, while the ARM version, some time in Q2 2013.

Intel and AMD can rub their hands as they both have extremely compact x86 processors fit for the tablet form-factor planned, and can woo tablet designers to opt for their solutions and get Windows 8 tablets instead of waiting for the ARM version of the operating system. Tablet vendors with mature ARM-based designs can always opt for Google's Android operating system, which will see no major competition for the greater part of this year.

SanDisk Corporation, a global leader in flash memory storage solutions, today announced it is working with key industry chipset vendors to help ensure a best-in-class user experience for mobile devices based on Microsoft Corp.'s upcoming Windows 8 operating system.

Companies such as Intel Corporation, Qualcomm Incorporated and Texas Instruments Incorporated (TI) are using SanDisk iNAND Extreme embedded flash memory with some of their top Windows 8 hardware development platforms. SanDisk is working with these companies to optimize its iNAND Extreme flash memory products with Windows 8-based tablet and mobile designs.

Microsoft is reportedly killing off two of its service brands, Windows Live and Zune. The two will be restructured and amalgamated with Windows 8 and its store. Windows Live has been a collection of optional services bound to the MSN/Live ID for Windows 7 that provides communication (Windows Live Messenger), calendar/planner (Windows Live Calendar), contacts, photo-organizer; Zune Music and Video player join them on the chopping block. These services will be instead come to be known as:

• Microsoft Account (Windows Live ID)
• Mail (Windows Live Mail)
• Calendar (Windows Live Calendar)
• People (Windows Live Contacts)
• Photos (Windows Live Photo Gallery)
• Music (Zune Music Player)
• Video (Zune Video Player)

Monitor connoisseur ViewSonic is said to be working on several Windows 8 tablets to complement its already available Android-powered ViewPad line. The Windows 8 devices are supposed to have a 10-inch touchscreen with a 'high resolution' which might mean (or, at least we hope it means) 1920 x 1200 pixels like on the upcoming Asus Transformer Prime TF700T.

Unfortunately there's no confirmation as to the platform (x86 or ARM) used by ViewSonic for the Windows 8 tablets. We'll probably have to wait until Computex for that info.

With Windows 8, Microsoft is introducing a new OS feature that works to improve performance and battery-life, called App Suspension. Simply put, it is a kernel optimization that "suspends" applications that are running in the background without much activity. This is done by freezing the machine to them, when suspended, an application no longer uses any CPU cycles, freeing up the CPU for other applications, and potentially reducing power consumption due to lower CPU activity.

The Windows NTOS kernel is a client-server type kernel, where processes and services function in a hierarchy as clients to the "server", which dispenses system resources to them. One would imagine a suspended process to be that which has no CPU time allocated by the kernel, which is probably told that the system is sleeping. This feature will be particularly handy for Metro applets, which in typical usage scenarios, will be running in the background most of the time. The feature could also come handy in scenarios such as gaming, where the OS could freeze supply of resources to useless processes.

On the sidelines of mobile computing's biggest annual international event, the Mobile World Congress (MWC), held in the end of February, Microsoft will hold a special event, titled Windows 8 Consumer Preview. The company sent out invites to the event, to its industry partners. The event will be held on the 29th of this month, and will be a two hour event in late-afternoon (3 PM - 5 PM). The synchrony of this event with MWC speaks volumes about the direction in which Microsoft is steering its OS business. Microsoft clearly wants to go big on operating systems for portable computing devices, and as such is converging this kind of OS with those for more powerful PCs. The convergence will at first be functional (similar UI, some inter-compatibility), and later structural (Windows-on-Windows ARM)?

Back in the 1990's, when the software industry knew the 32-bit x86 address-space limitation was closing in, they geared up for transition to another machine architecture, then came AMD64 and EM64T, which allowed an x86 processor to perform in both 64-bit and 32-bit modes. Microsoft didn't want users of its 64-bit Windows to be deprived of using software coded for 32-bit Windows, which was infinitely more in number than 64-bit software. Hence it developed what is known as Windows-on-Windows 64 (WOW64), a translation layer that interfaces 32-bit software and drivers to the 64-bit OS and drivers. With its next major Windows version, Windows 8, Microsoft wants to give the ARM architecture a big push, with a Windows 8 version for ARM computing devices (such as tablets and netbooks). Guess what?

A latest bulletin at MSDN hints at the possibility of Microsoft working on a x86-to-ARM translation layer, which allows you to run desktop windows (Win32) software on Windows 8 ARM, effectively "Windows-on-Windows ARM". Without specifically pointing out the ability to run Win32 software on ARM, the bulletin mentions the ability to run non-metro applications (native Windows) on SoC (system-on-a-chip) architectures. It could also just be a reference to Intel's single-chip SoCs such as Medfield, which are x86-based. If Microsoft pulls off a "WOWARM", it could spell terrible news to Intel, because something such as the hypothetical WOWARM is all that stands between ARM and high-performance desktop PCs. In a market that only has two other competitors (AMD and VIA), dozens more could join in overnight, including NVIDIA's karmic entry after being shunned off an x86 license.

The Ivy Bridge LGA1155 processors inbound for April are mom and pop PC chips in front of the monstrosities Intel has planned for the enterprise (and possibly high-end desktop/HEDT) markets, based on the architecture. An 10-core Ivy Bridge-EP engineering sample, made it to the right hands in Taiwan (wrong hands for Intel), that wasted no time in putting them through some tests.

The 10-core Ivy Bridge-EP/EX chip (LGA2011, 2P-capable) features 10 next-generation cores clocked at 2.80 GHz, with 256 KB L2 cache per core, 30 MB shared L3 cache, and HyperThreading technology that enables 20 logical CPUs. This chip crunched WPrime 1024M in 158.5 seconds, and scores 41.78X relative speed in Fritz chess when just 8 of its 20 threads are put to use. You can also find some pretty screen shots of CPU-Z with its long processor selection list and Windows 8 task manager.

It's no secret that Microsoft's proprietary gesture-recognition technology it originally launched on the Xbox platform, is making its way to PCs, as software developers have access to Kinect for Windows SDK. What's interesting, though, is that soon people won't need a creepy-looking three-eyed device facing them to recognize their gestures. They will, instead, be embedded into notebook display bezels the way web-cameras are.

The Daily reports that it has seen a pair of notebook prototypes that appeared to have been "ASUS notebooks running Windows 8," with their web-cam replaced by a row of optical sensors on top of the screen, and a row of LEDs said to be at the bottom. Some might think that this is ASUS' very own Kinect-alternative WAVI Xtion, but The Daily also confirmed with a source at Microsoft that these prototypes are indeed of notebooks that are Kinect-enabled.

Very quietly Microsoft has released two new patches available for the Bulldozer platform. According to the AMD blog these patches seem to offer little more then a 10% boost but the do improve over all performance. This is what Adam Kozak a product marketing manager at AMD had to say,

"Some of you may remember that AMD FX processors use a unique dual-core module architecture codenamed "Bulldozer", which current versions of Windows 7 were not specifically architected to utilize. In essence, for those with an AMD FX-8150 Processor, for example, Windows 7 sees the eight available cores and randomly assigns threads to them.

In initial testing of the upcoming Windows 8 operating system, we've seen performance improvements of up to 10% in some applications, when compared to Windows 7. This is because the system correctly recognizes the AMD FX processor architecture and cores. Thanks to close collaboration between Microsoft and AMD, Microsoft recently completed back-porting some of the Windows 8 scheduler code for AMD FX processors into a hotfix for Windows 7."

Lenovo today announced IdeaPad YOGA, the industry's first multi-mode notebook with a 360 degree flip-and-fold design. Combining the tablet's ease-of-use with the ultrabook's functionality, IdeaPad YOGA gives consumers four-in-one personal computing, with four separate usage modes in one PC. Lenovo also announced today its new IdeaCentre A720, the slimmest 27-inch all-in-one (AIO) PC in the industry.

c|net has tried out a laptop prototype from Tobii at the Consumer Electronics Show, that can be controlled with the eyes - and it works. The reporter, Rafe Needleman, was initially sceptical, as the eyes are only designed for input not output, but it turned out to be very fast and intuitive for him. It works by having the user press the Windows key, look at a tile and then release the key to activate the tile. The use of the keypress prevents one's eyes, which tend to dart around in normal use, from scrambling input to the laptop. As the user's gaze darts over the screen, the system gives an indication as to which tile is currently selected by the user's gaze to ensure accurate tile selection by the user.

To achieve this feat, the modified laptop uses two infra red emitters and two special IR cameras along the Windows 8 customer preview released a while back. They use "the reflective point of the retina, plus the glint off the cornea" Rafe was told. From this, the computer builds a 3D model of the user's gaze to work out where they are looking on the screen. Rafe concluded, "I did not expect to like it, but I did. It is intuitive to use, and very fast. Tobii has done a good job of making your glances into workable input signals."

In the latest Building Windows 8 blog post (published yesterday) Microsoft is talking about the options available to 'rekindle' the flame of a Windows 8 install. These options include the definitive Reset, which will basically re-install Windows and remove all personal data, apps, and settings from the system, and the less 'damaging' Refresh, which will reinstall Windows or restore a previously-created image of the OS, while keeping data, settings, Metro style apps and such, untouched.

According to Digitimes' upstream supply chain sources, two Top 5 PC makers, Lenovo and Acer, are planning to introduce in the third quarter of this year some Wintel tablet PCs based on Intel's Clover Trail platform.

Clover Trail is the third Atom platform to utilize 32nm chips, and it specifically targets tablets, offering higher performance than the Medfield SoC coming in the first half of this year.

Both Acer and Lenovo's alleged Clover Trail tablet PCs are expected to run Windows 8 and may focus on the enterprise market.

Some time in June 2010, Apple filed a patent application for a unique new facial-recognition technology that's light on the resources. It was discovered by AppleInsider. Entitled "Low Threshold Face Recognition," the application defines a method of recognizing a person using a front-facing camera of a device (could be anything from an iPhone, iPad, to even a Mac or Macbook), that consumes very little system resources, and is hence light on the device's power source.

It could very well be an evolution of the "Slide to Unlock" mechanism found on iOS devices, and conventional password entry to wake Macs up. If granted, this technology comes to being at a particularly important time, when a similar technology evolving out of Android Face Unlock, and when facial-recognition will be a key feature of Microsoft's Windows 8 operating system, to log into systems and wake devices up from their e-slumbers. Apple's proposed technology relies on analyzing a "high information portion" portion of the human face, rather than using the conventional resource-heavy method of recognition. Apple claims its technology will be just as reliable.

According to the latest information received by industry observer DigiTimes, Intel plans to launch the first processor platform for ultra-thin Android tablets based on its x86 architecture, codenamed "Medfield", in Q2 2012. Tablets based on this will be able to run Android 4.0 "Ice Cream Sandwich". Then in Q4 2012, Intel plans to launch the more powerful Clover Trail-W platform. Currently, Intel's Oak Trail platform consisting of Atom Z670 processor and SM35 chipset drive Windows 7 or Android Honeycomb tablets.

The fundamental difference between Medfield and Clover Trail-W with its predecessor Oak Tail, is that Medfield will be designed for ultra-thin tablets with long batter life, currently only ARM processors provide the kind of performance-per-Watt to achieve this form-factor. Oak Trail and its succeeding Clover Trail-W, are designed for slightly more capable tablets. Oak Trail is opted today, to design tablets that run Windows 7 PC operating system. Microsoft will design performance and UI-optimized Windows 8 variants when its next-gen operating system sees the light of the day next year.
