URI handler opens links and pictures in MS Word about abaddon HOT 3 OPEN

i simply use gtk_show_uri_on_window. GSmartControl seems to carve out an exception for win32 that calls ShellExecute. i could do the same but having it open word is bizarre.
i believe gtk (gio) gets it from HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice (and http\UserChoice) in the registry. maybe check that? or also in control panel, "Associate a file type or protocol with a program"

from abaddon.

Control panel was first thing I looked at, nothing too extraordinary there. The handler for .url files was set to "Browser by Microsoft Corporation" (not even to Internet Explorer, idk what that even is). I changed it to Chrome - that didn't do anything.

The registry keys Progid are both set to ChromeHTML as they should. I noticed that the ChromeHTML class was under HKLM\software\classes and not under corresponding HKCU (as the browser is installed for all users), so I tried copying that subtree into HKCU\Software\classes\ChromeHTML. That didn't do anything.
