Windows, dockerd

The question about the official document on how to config the Windows’s dockerd

On official document, Windows 10, Docker Desktop version 20, I have set all hidden files could be seen, but I still can not find the C:\ProgramData\docker\config\daemon.json. Instead, I found the same name file in C:\Users\user\.docker\daemon.json, I tried to change it to look like what your document said:

 "debug": true,

  "tls": true,

  "tlscert": "/var/docker/server.pem",

  "tlskey": "/var/docker/serverkey.pem",

  "hosts": ["tcp://"]


  "builder": {

    "gc": {

      "defaultKeepStorage": "20GB",

      "enabled": true



  "experimental": false,

  "features": {

    "buildkit": true


but the Docker Service could not be started, so could someone give me some advice on that? Thanks for your help!
