Hi Christoph,

Glad you are tapping into another favorite subject of mine (Windows file

HKEY_CLASSES_ROOT is a merged view that is supposed to be read from only.
Instead put the keys under HKEY_CURRENT_USER\Software\Classes\ and it
should work equally well and only apply to the current user. Writing the
keys will therefore also not require elevated privileges.

Kind regards,
