why not - I just mean don't use it if you don't have to!

the reg query … returns only one value in the form of

   Applications\ConTEXT.exe            

where you can strip the first part by 

FOR /f "tokens=3*" %%a IN (
  'REG QUERY
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ly\userchoice'
) DO IF NOT [%%a]==[] FOR /f "tokens=2* delims=\" %%a IN ("%%a") DO (SET
editor=%%a)

then it is a temporary environment variable which you can get via (getenv
"EDITOR")
