Microsoft Windows 8 Developer Preview
Experience first-hand what Microsoft Windows 8 has to offer.
The Windows Developer Preview is a pre-beta version of Windows 8 for developers. These downloads include pre-release software that may change without notice. The software is provided as is, and you bear the risk of using it. It may not be stable, operate correctly or work the way the final version of the software will. It should not be used in a production environment. The features and functionality in the pre-release software may not appear in the final version. Some product features and functionality may require advanced or additional hardware, or installation of other software.
For additional information here's what's new in Windows 8 developer preview - what you need to know.
Touch-First User Interface
- Metro style. Windows 8 introduces a new Metro style interface built for touch, which shows information important to you, embodies simplicity and gives you control. The Metro style UI is equally at home with a mouse and keyboard as well.
- Touch-first browsing, not just browsing on a touch device. Providing a fast and fluid touch-browsing experience, Internet Explorer 10 puts sites at the center on new Windows 8 devices.
More Ways to Engage With Powerful, Connected Apps
- Powered by apps. Metro style apps built for Windows 8 are the focal point of your experience, filling your entire screen so there are no distractions.
- Apps can work together. Apps communicate with each other in Windows 8. For example, you can easily select and email photos from different places, such as Facebook, Flickr or on your hard drive.
- Your experience syncs across your devices. Live roams all the content from the cloud services you use most — photos, email, calendar and contacts — keeping them up-to-date on your devices. With SkyDrive, you can access your files, photos and documents from virtually anywhere with any browser or with Metro style apps in Windows 8.
- The best of Windows 7, only better. Windows 8 is built on the rock-solid foundation of Windows 7, delivering improvements in performance, security, privacy and system reliability. Windows 8 reduces the memory footprint needed — even on the lowest-end hardware — leaving more room for your apps.
- Preserving power-user favorites and making them better. For those who push the limits of their PC, Windows 8 features an enhanced Task Manager and Windows Explorer and new, flexible options for multimonitor setups.
New Developer Opportunities
- Windows Store. The Windows Store will allow developers to sell their apps anywhere Windows is sold worldwide, whether they’re creating new games or familiar productivity tools.
- Build using more languages. Windows 8 lets you leverage your existing skills and code assets to create great experiences using the programming language you prefer.
- Rich hardware integration leads to richer experiences — particularly for games. DirectX 11 gaming power underlies Windows 8, allowing the easy creation of full-screen games with smooth, flicker-free action.
New Generation of Hardware
- One Windows, many shapes and sizes. Support for ARM-based chipsets, x86 (as well as x32 and x64) devices, touch and sensors means Windows 8 works beautifully across a spectrum of devices, from 10-inch tablets and laptops to all-in-ones with 27-inch high-definition screens.
- Always connected. With Windows 8, new ultrathin PCs and tablets turn on instantly, run all day on a single charge and stay connected to the Internet so your PC is ready when you are. Next-generation system on a chip (SoC) support will also enable greatly extended standby and low-power states.
- Tap the full power of your PC. Windows 8 runs on PCs and is compatible with the devices and programs you use today on Windows 7, without compromise, to deliver the performance you expect of a PC.

How to install the Windows Developer Preview from an ISO image:
The Windows Developer Preview is delivered as an .iso image that must be converted into installation media stored on a DVD or a USB flash drive. On Windows 7, the easiest way to convert this file is to use Windows Disc Image Burner. On Windows XP and Windows Vista, a third-party program is required to convert an .iso file into installable media—and DVD burning software often includes this capability.
Note: The .iso file that contains the developer tools requires a large capacity DVD called a DVD-9, as well as a DVD burner that can handle dual-layer (DL) DVDs. Most modern burners should be able to handle this format.
