Windows 8 hardware requirements

Microsoft has been releasing the hardware certification requirements for upcoming operating systems for many years now, and the latest guidelines to be quietly detailed cover tablets running the upcoming operating system, due for launch later this year.

The information was recently spotted by Within Windows, although Microsoft published the documents quietly in December without any further announcement. The information contains Microsoft’s minimum hardware guidelines in order to successfully meet Windows performance, quality and feature criteria to provide an optimum experience using Windows 8.

Some of the requirements make perfect sense, like the NFC “touch mark” concept. In order to successfully pass validation, any tablet with Near Field Communication (NFC) will be required to have either a sticker, or be embossed in some form with the location of the NFC chip to make the experience of pairing it with the NFC readers easier.

Microsoft also requires all tablets to feature exactly five buttons. They are for power, rotation lock, volume up, volume down and a Windows button. The Windows key must be at least 10.5mm in diameter although it is the manufacturer's own preference for its shape.

As Windows users will have become accustomed to over the years, the CTRL + ALT + DEL method will be replaced with the new combination of using the power + Windows button.

The minimum hardware requirements have also been detailed as follows:

Storage: capacity must have at least 10GB of free space after installation of the operating system
The system firmware must use UEFI, and have secure boot locked down for ARM tablets
Network: WLAN and BlueTooth 4.0 + LE (low energy)
Mobile broadband: If fitted, an assisted GPS radio is also required
NFC: A visual marking of its location on the outer body is required
Graphics: Direct 3D 10 device with WDDM 1.2 driver
Display: Must be at least 1366x768 pixels at a depth of 32bits
Touch Support: It must pass all tests offering at least five touch points
Camera: Must all be capable of at least 720p
Ambient light sensor: 1-30k LUX capable with dynamic range of 5-60K
Sensors: Magnetometer, accelerometer and gyroscope
Connectivity: At least one USB 2.0 controller and exposed USB 2.0 port on frame
Speakers
Microsoft also requires that all tablets running Windows 8 support no-reboot upgrades of WDDM graphics drivers, as well as a two second resume time from standby. Although only Intel-based Windows 8 tablets are required to do this, ARM models will likely have this feature added as it matures on the Windows platform.

One aspect that will likely cause considerable negative feedback is a mandatory Secure Boot feature for ARM-based Windows 8 devices, preventing users from loading alternative operating systems such as Android. Intel-based tablets will not be required to be locked down in the same manner.


There is no word on minimum processing power, or RAM requirements but more details will emerge as we draw closer to the launch of Windows 8.

Can Microsoft Windows 8 Fail?

In anticipation of the Windows 8 release, there has been speculation on Microsoft's future. Will the company break out of its slump? Will it get a new image? How will Windows 8 do? What if nobody likes it? What happens next?
Let's get a few things straight. Even if Windows 8 is a huge dog and bombs the way Vista did, it will not matter. There is still nothing out there that can take Microsoft out of the game. Apple has the only other quality operating system out there, and it is proprietary and still more expensive. Money and cost are important.

 Linux may have a chance, but it is held back by all sorts of factors. I've been using Linux but still prefer Windows. The reasons are minor, except for the fact that Adobe refuses to put its Creative Suite on Linux, where it could probably perform faster. A Linux box, as it now stands, is good for light word processing, order entry, and Web surfing. It would be perfect in certain office environments.
The Linux OS also has a peculiar feel that is hard to explain but it never feels the way Windows and Macintosh feel. This is something that concerns me because I cannot put my finger on it. Others will say the same thing.
The backstory: The programming language Forth that creates code gives me the same dubious feeling. I always get into trouble when I mention this, but since the 1980s, I've complained about it. It's a specialty language that seems to be popular to this day among people who write code for control mechanisms. Every so often, a desktop application shows up coded in Forth and I generally spot it because of its muddy feel. There is no other way to describe it. It is very subtle but uncomfortable.
Digital Research had one of the first PC-oriented GUIs called GEM that predated Windows. Microsoft is credited with destroying it in the market when Bill Gates personally went around telling people not to use it because Windows was going to be better, which it wasn't, until years later. This didn't matter, though. I used GEM and it was extremely muddy. Trying to use the unresponsive pointer was as frustrating as trying to control a helium balloon.
The point is that Microsoft and Apple both got the feel right and have maintained that edge over everything else that has since come along.
Before Microsoft ever fails in the marketplace, many things have to happen. Mainly, Microsoft has to shoot itself in the foot over and over, not just once or twice. It doesn't tend to do this. It will botch a product such as Vista or Windows ME and come right back with a fixer like Windows 7 or Windows 2000. Losing ideas such as the Zune, Microsoft Bob, or its VCR had very minimal impact on the company. The failure list for Microsoft is a long one, but its cash cows have continued to pump profits out.
