Microsoft demoed their upcoming Windows 8 OS during the BUILD conference today along with the sneak peek to developers platform and tools. Windows 8 includes plethora of new features which includes the all new immersive Metro style UI, Internet Explorer 10 (IE10), Task Manager, Quick boot, Face password, Cloud integration etc. They also made available the Windows 8 Developer Preview copy to all the attendees out there along with a Samsung Tablet so that the developer community can play with it and give feedback before the RTM hits store. And for the rest of us the very same files will be uploaded to their public servers and will be available soon.
The new interface is primarily designed for 16:9 screen resolutions, with 1366×768 and larger screens able to display two Windows 8 applications. 1024×768 screens can display one Windows 8 application in full-screen, and 1024×600 screens can only use the traditional Windows desktop. Mike Angiulo confirmed at Computex 2011 that Windows 8 will use OEM Activation 3.0 instead of OEM Activation 2.1 (used by Windows 7), which supposedly makes it less prone to cracks. Windows 8 features a new lock screen that shows the date and time and notifications, along with a customisable background.
Windows 8 will also include Microsoft's Hyper-V virtualization tool. Previously only offered in Windows Server, Hyper-V will now be available in client versions of Windows for the first time. The system requirements for Hyper-V are a 64-bit processor, a 64-bit version of Windows 8, and a minimum of 4 GB of RAM. Hyper-V also requires a 64-bit system that has Second Level Address Translation (SLAT), a feature that helps with memory management. Many of Intel's and AMD's recent processors support this feature, including many of Intel's i-Series processors (with Extended Page Table) and AMD's 10h family processors. On September 8, 2011, Microsoft announced that Windows 8 has short boot times, because it saves the kernel's memory to the hard disk on shutdown (similar to the existing Hibernate option) and reloads it on startup.
