Windows 10: Please help me remove a leftover of an uninstalled app

Please help me remove this leftover "item/registry junk" or whatever it is, from the "How do you want to open this file?" apps list. I uninstalled that software, but it is still in the list for opening my BDMV, M2TS, MPLS files. The wierd "leftover" just shows a location of an already uninstalled video player. I have marked the wierd phenomenon.

Thank you.
(I apologize, but I really dont know how else to explain. On another forum people had "problems" understanding longer sentences...I hope that will not be the case here too.)

PLEASE HELP ME GET RID OF A WINDOWS APP!!

I want to have my photos ALL go to photoshop elements 15, and some can; however, some are still hung up with that view slide show and I can't get at them to fit them into the book I am writing and need them for. When I scan them with my Canon Scanner
they again get hung up, but I will work on that and see if I can wrest my scanner away from the VERY DESTRUCTIVE windows app.

 

PLEASE HELP ME GET RID OF A WINDOWS APP!!

Hey Les. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Go to Settings > Apps > Default Apps, under Photo Viewer choose Photoshop app you installed.

This should cover it. If not let us know.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

 

You want to delete this lot in the registry using regedit: Code: [-HKEY_CLASSES_ROOT\.xxxxx] [-HKEY_CLASSES_ROOT\SystemFileAssociations\.xxxxx] [-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.xxxxx] [-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Roaming\OpenWith\FileExts\.xxxxx][/quote] Changing xxxxx for the file types (like BDMV, M2TS, MPLS) you are interested in.

Ask in this thread if I'm not clear as it covers removing default associations: Restore Default File Type Associations in Windows 10 - Page 25 - Customization Tutorials

 

Thank you so much! While I was searching the registry for the items you listed, I actually found the culprit!
There is a ton of "mpc-be.xxxx" items that are from the old Kawaii Codec Pack Black, in the HKEY_CLASSES_ROOT\

Im gonna delete all of them now.

 

Oww lol! I just needed to reinstall Kawaii Codec Pack Black (KCP) and uncheck all file associations in its MPC-BE. I did that and it was gone, I didnt have to edit the registry.
