What exactly is Windows Sandbox?

Windows Sandbox is a virtual desktop environment that is used only temporarily. When you run Windows Sandbox, you’re essentially running a clean version of your operating system in which your actions do not affect the rest of your PC.

So, the Windows Sandbox provides a protected environment in which you can test any software before installing it on your primary device. When you close the sandbox, all activity is destroyed before returning to the host machine.

How Does Windows Sandbox Function?

Microsoft employs several tools to bring Windows Sandbox to life.

  • Dynamic image generation: The Windows Sandbox creates a virtual computer by copying an image of your present operating system. Your Windows Sandbox environment always runs a fresh, clean installation of Windows 10 with the most recent updates. Nevertheless, unlike other virtualization technologies, you do not need to store an extra copy of the operating system to boot into.
  • Intelligent memory management: Virtual machines can consume a lot of resources and require the host machine to share its hardware. Windows Sandbox employs intelligent memory management to dynamically allocate memory between the host and the sandbox, ensuring that the host does not stall.
  • Snapshot and Clone: To reduce the strain on the host system, Windows Sandbox employs two common virtualization technologies known as Snapshot and Clone. The snapshot enables Windows Sandbox to boot the environment once and then “save the memory, CPU, and device state to disk.” The environment can then restore from the disc rather than booting it each time a new instance of the sandbox is required.

Windows Sandbox also makes use of better graphics virtualization to provide a smooth experience that mirrors the host.

Prerequisites to Run Windows Sandbox

Windows Sandbox is presently available for installations of Windows 10 Pro or Enterprise running Insider Preview build 18305 or later, or the Windows 10 May 2019 upgrade or later. Windows Sandbox will not be available to Windows 10 Home users.

You will also require:

  • Virtualization of a 64-bit processor enabled in your system BIOS
  • A minimum of 4GB RAM is required (Microsoft recommends 8GB)
  • 1GB of free disc space is required (Microsoft recommends using an SSD)
  • A minimum of two CPU cores (Microsoft recommends four cores with hyperthreading)

What is the source of the Windows Sandbox failed to start error?

There could be several reasons why the Windows Sandbox is not operating; some of the most prevalent are listed below:

  • Services deactivated: If the Sandbox-related services are disabled, Windows Sandbox will not start. You must guarantee that the services and dependencies that are responsible for the functionality are operational.
  • System files have been corrupted or are missing: If the system files are corrupted, the Sandbox may not start. To resolve the issue, use Command Prompt to repair the system files.
  • The system requirements are incompatible: To run Sandbox, your system must meet the minimal hardware requirements. Otherwise, you may encounter this error.
  • Sandbox feature not activated: Windows Sandbox may not start if the Sandbox feature is not chosen from the Windows Features list.
  • Antivirus software from a third party: Certain security applications may interfere with the Sandbox’s operation. You may need to temporarily disable your antivirus.
  • Old graphics driver: If your graphics driver is old or obsolete, you may experience this problem. To resolve the issue, you must install the most recent drivers.

What can You do to fix the Windows Sandbox failed to start error? 

Before proceeding with advanced troubleshooting, you should do the following checks:

  • Examine Windows updates.
  • Temporarily disable your security software.

The error code could be 0x80070057, 0x800706d9, 0x80070002, 0x80070569, 0x80072746, or 0xc0370106 in rare situations.
