Microsoft has introduced Windows 10X, a streamlined version of Windows designed specifically for dual-screen devices like the upcoming Surface Neo. Developers can now access a pre-release build to test and optimize their applications for this new platform.

Although Windows 10X isn't available as a standalone operating system, you can experience it using the Microsoft Emulator, which simulates the OS as if it were running on actual hardware.

Requirements

  • Windows Insider Preview build 10.0.19555 or later.
  • Intel® CPU with at least 4 dedicated cores (or multiple CPUs totaling 4 cores).
  • 8 GB of RAM or more; allocate 4 GB for the emulator.
  • 15 GB of free disk space for the VHDX and differential disk (SSD recommended).
  • Dedicated video card recommended:
  • DirectX 11.0 or later.
  • WDDM 2.4 graphics driver or later.
  • Enable the following features in BIOS:
  • Hardware-assisted virtualization.
  • Second Level Address Translation (SLAT).
  • Hardware-based Data Execution Prevention (DEP).
  • Ensure the Hyper-V feature is enabled on your system.
