Windows – cmd command to set Chrome as default browser Windows 10

From the terminal, use

sudo update-alternatives --config x-www-browser

This will provide a list of installed browsers, similar to the following (which is mine):

There are two alternatives which provide `x-www-browser'.
Selection    Path                         Priority    Status
-------------------------------------------------------------
* 1          /usr/bin/chromium-browser    40          auto mode
  2          /usr/bin/firefox             40          manual mode

Press enter to keep the current choice[*], or type selection number:

Just hit the selection number for the browser you want.

This command will set IE as the default browser:

shmgrate.exe OcinstallreinstallIE

This policy should stop people determining the default browser.
