Windows Sandbox failed to start, The system cannot find the file specified

There are three methods that will help you if Windows Sandbox failed to start or load with error code 0x80070002 or 0x80072746. They are as follows:

1. Check for Windows Updates.
2. Enable all the Services required by Sandbox
3. Enable Virtualization, Hyper-V, and SLAT support.

1] Check for Windows Updates

Check for updates for your computer. Maybe Microsoft has released fixes or driver updates for your system.

2] Enable all the Services required by Sandbox

Open the Windows Services Manager. Here, for the following 5 Windows Services, ensure that the Startup type is set to as what is given below. If you want, you can Start or Restart these Services in this order:

1. Network Virtualization Service. (Startup type: Manual).
2. Virtual Disk. (Startup type: Manual).
3. Hyper–V Virtual Machine. (Startup type: Manual).
4. Hyper–V Host Computer Service. (Startup type: Manual).
5. Container Manager Services. (Startup type: Automatic).

Having ensured that these Services are running, you can run Windows Sandbox again now.

3] Enable Virtualization, Hyper-V and SLAT support

Virtualization, Hyper-V, and SLAT support are three main interconnected pillars that support the running of this Windows Sandbox feature.

Make sure that your computer supports Virtualization and it is turned on.

You also need to enable Hyper-V on your computer.

Also, make sure that you have the SLAT or Second Level Address Translation support enabled on your CPU.

Even if one of the components mentioned above have a bad configuration or are not available, there will be trouble running Windows Sandbox, and the only fix would be to upgrade the specifications of your computer.

All the best!
