WSL2 on Microsoft Surface Pro X

I purchased MS Surface Pro X and updated Windows to Version 1903 (OS Build 19018.1) using the Insider Program. I followed the WSL2 doc and installed Ubuntu 18.04 for ARM.

You are absolutely NOT running Windows 10 version 1903. There are multiple reasons I know what version you are actually running.

However, your inability to run WSL from a PowerShell prompt is a known issue, you need to run it from a command prompt.

If you are using an Arm64 device and running this command from PowerShell, you will receive this error. Instead, run wsl.exe from PowerShell Core, or Command Prompt.

It appears that in the future Hyper-V will be supported on ARM devices once Windows 10 version 2103 is released.
