Slight issue with this batch script. ftype command is only aware of the following registry key:
HKCR\htmlfile\shell\open\command\(Default)
Which means that the user's browser choice or other custom choices are not reported correctly.

It does not see:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\<extension>\UserChoice
Which can have a different application that the user might have selected.
