I don't have a real methode i just only have a messy script which deletes the folder which include the XXX.inf Inbox-Driver names form FileRepository, WinSXS and INF. This works "a little" but is "quick" and dirty. All registry-settting are still in the Hives. Also there are some weird behavior. I analysed the DISM with procmon an did some checks between and 3rd party and inbox driver within this files, and i saw some "flag" but i can't remember... but anyway dism didn't wanted to remove the driver an the /get-drivers listing was uncompletet after editing the files (it had some output and stoped in the middle with an error) I removed a big "core-driver-component" which was possible with install_tweak_wim but than absolutly nothing worked anymore. I have my old, little sorted, resource files. If you interessted i can send them to you / upload them. There you might can see what happend...?!
