The old control.exe stopped working for me today. I changed it to ms-settings:defaultapps.
Set WshShell = WScript.CreateObject("WScript.Shell")
' Open the default settings window
WshShell.Run "ms-settings:defaultapps"
WScript.Sleep 5000 ' Wait until open (adjust if necessary)
' Adjust number of tabs until you reach the browser choice setting
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
' Open the browser choice menu
WshShell.SendKeys " "
WScript.Sleep 500 ' Wait until open
WshShell.SendKeys "{TAB}" ' Move down one selection
WshShell.SendKeys " " ' Set current selection as default browser
WScript.Sleep 500 ' Wait until open
' Uncomment the line below to outomatically close the settings window
WshShell.SendKeys "%{F4}"
WScript.Quit
