Cannot find the daemon.json file in windows 10 after docker-desktop installation

Right click Docker icon in taskbar > Click Settings > Click Docker Engine

You can update that, and it should work. I'm on Docker Engine v19.03.8.

The path C:\ProgramData\Docker\config\daemon.json, as described in Microsoft documentation, is correct, or also correct.

I think the file is not created until you change it on GUI. Once you change it on GUI,the file will be were is supposed with the exact content you apply.

On my system the file is at %userprofile%\.docker\daemon.json.
