  Windows 10 Technical Preview for Enterprise works great on the same hardware that powers Windows 8.1:
  • Processor: 1 GHz or faster
  • RAM: 1 GB (32-bit) or 2 GB (64-bit)
  • Free hard disk space: 16 GB
  • Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
  • A Microsoft account and Internet access
  Additionally:
  • To access the Windows Store and to download and run apps, you need an Internet connection, a screen resolution of at least 1024 x 768, and a Microsoft account.
  • After you install the preview, you won't be able to play DVDs using Windows Media Player.
  • Technical Preview is not supported on Windows RT or Windows Phone devices.
  • For 64-bit installations of Technical Preview for Enterprise, a small number of older PCs may be blocked from installing the preview because they don't support CMPXCHG16b, PrefetchW, and LAHF/SAHF.
  • To use touch, you need a monitor that supports multitouch.
  • The preview works best with a mouse and keyboard. Improvements to touch will appear in future updates.
  Windows 10 Technical Preview for Enterprise is available in English, Chinese (Simplified), and Portuguese (Brazil). If you're running Windows 8.1, Windows 8, or Windows 7 and your system language isn't English, Chinese (Simplified), or Portuguese (Brazil), you can only keep your personal files when you upgrade. You won't be able to keep your apps or Windows settings.

  Important: Windows Update will be set to automatically install important updates as they become available. You won’t be able to turn off automatic updates in Technical Preview, but you will be able to choose between a fast or slow update cadence. To change when preview builds are installed, open PC settings, click Upgrade and recovery, click Preview builds, and then click Change the time my PC installs preview builds.
