Windows Media Center functionality will be available only for Windows 8 Pro, as a paid "Media Pack.
Windows 8 Enterprise Windows 8 Enterprise provides all the features in Windows 8 Pro, with additional features to assist with IT organization (see table below).This edition will only be available to Software Assurance customers. Windows RT Windows RT will only be available pre-installed on ARM-based devices such as tablet PCs, and was named for the Windows Runtime (WinRT) development platform that Microsoft is introducing in Windows 8.It will include touchoptimized desktop versions of the basic set of Office 2013 applications to s—Microsoft Word, Excel, PowerPoint, and OneNote, and device encryption capabilities.

Similar to Microsoft Office 2010 and Windows Live Essentials, the re-designed File Explorer (re-named from Windows Explorer) uses the Ribbon interface to enhance discoverability of commands and bring relevant commands to s depending on their file selection. For example, selecting photos in a folder brings up tools to rotate the photos and to start a slide show. The interface was selected to bring forward the most commonly used commands for easy access. File Explorer can now mount ISO, IMG, and VHD files as virtual drives through simple right-clicks or the Explorer toolbar[12] as compared to Windows 7 where VHDs could be mounted in a less-discoverable way, via the Disk Management section in the Computer Management MMC, or by using diskpart from the command line.

New to Windows 8 are two new recovery functions, named Refresh and Reset, both of which make a complete restore easier than a re-installation. The former keeps all settings and files of the intact and only reverses all changes to Windows files to its original state and removes all installed programs and apps.

s do not have to be localonly anymore, but can be linked up to one's Microsoft . This has the advantage that s will not lose their settings and files, as they move from their home computer to their work laptop or to any other computer also using Windows 8, and g in via their Microsoft .
Windows To Go is an Windows 8 Enterprise feature that will allow s to create a bootable USB Flash drive (usually called a Live USB) with Windows 8 in it, including the 's programs, settings, and files. It is planned to work on both USB 2.0 and USB 3.0, and both on legacy BIOS and UEFI firmware.
Storage Spaces is a storage virtualization technology which succeeds Logical Disk Manager and allows the organization of physical disks into logical volumes similar to Logical Volume Manager (Linux), RAID1 or RAID5, but on a higher level. A storage space will behave like a physical disk to the , with thin provisioning of available disk space. The spaces are organized within a storage pool, i.e. a collection of physical disks, which can span multiple disks of different sizes and different interfaces (USB, SATA, SAS).
The process of adding new disks or replacing failed or older disks is fully automatic, but can be controlled with Power Shell commands. The same storage pool can host multiple storage spaces. Storage Spaces have built-in resiliency from disk failures, which is achieved by either mirroring or striping with parity across the physical disks. Each storage pool on the ReFS filesystem is limited to 4 PB (4096 TB), but there are no limits on the total number of storage pools or the number of storage spaces within a pool.
Windows 8 will have built-in of USB 3.0 for better power management and longer battery life
Windows 8 will System on a Chip (SoC) architectures, including ARM-based systems. On the x86 architecture, Intel Corporation and AMD continue their work on low-power SoC designs that Windows.
Windows 8 will also include Microsoft's Hyper-V virtualization software. 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.
Microsoft announced that Windows 8 has short boot times, in part because it saves the kernel's memory to the hard disk on shutdown (similar to the existing hibernate option) and reloads it on start up. Also because of for many cores during boot
Internet Explorer 10 is included as both desktop program and as a touch-optimized app. The latter does not plugins or ActiveX components, but includes a version of Adobe Flash Player that is optimized for touch and low power usage and works only on sites included on a white list. Windows Store will be the only method of purchasing and ing Metro-style apps, as well as advertising desktop apps. Metro-style apps are installed from the Windows Store, or in the form of a Line Of Business app on devices ed in a network domain.
