Windows 10: How to delete specific entry in windows file open popup?

Hello everybody,
Does anyone know what does "%1" means in windows file open popup, or what program causes it? I think it's associated with picture file types (jpg, png, gif...) but I don't know how to fix it.

Is there any way to delete it or find what program causes it and fix it by re/uninstalling that particular app?





Thanks in advance *Smile

How to delete an entry in Open With menu?

I have opened an mp3 file with a program mistakenly and that program keeps showing in the Open With list selection for every other extensions that I right click and go to Open With menu from that time on, how can I delete that entry through registry editor?

 

How to delete an entry in Open With menu?

I meant the Other Option drop-down when you click "Choose another app" drop-down





For example if you click "Look for another app in PC" link in the end and choose a program, that program like Paint and Notepad always appear in this list for any file type and that's quiet annoying and unprofessional and it is not removable by regedit, let
me make other remarks about Microsoft faults. Unfortunately most of apps in start menu like Weather, insider hub, People and etc are not removable and XPS service is not removable in Optional Features if you do that, also Guest account is not working and by
enabling it, it doesn't login and don't appear in the menu also many other unprofessional things and mistakes that should be covered and unfortunately they make and give out instead of testing through everything and actually most of people don't need extra
features that is feeble in Windows and full of bugs, no one excepted Microsoft just create Windows quickly that becomes a version like 8 that forces it to make 10 for it's faults. Microsoft Edge was another junk like Groove that IE and WMP have the same functionality
and instead of making them into one they just created other type of them.

 

Hi, often %1 is used to designate a parameter in a command line, but shouldn't appear in that dialogue. To remove it you need to edit your 'Open With' list.

In the registry there's an 'Open With' list for EACH File extension.
So definitively removing this is a bit harder, as if you delete one instance, for one file type, there could be others. So you'd have to search for them.

Basically this is a registry job.

"The “Open with” dialog box recommends programs to open a given file. The contents of the Recommended Programs list are determined in part by the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\<filetype>\OpenWithList (where filetype is the extension of the file type in question). So, for example, the …\.bmp\OpenWithList key may include several values, such as Notepad.exe. Deleting the unwanted item in the OpenWithList key will remove it from the Recommended Programs list.

Some items in the Recommended Programs and Open With lists appear as the result of values within the HCR\filetype key and its subkeys. However, accidental additions to the lists are always made in the HKCU hive."

I recommend 'Regscanner' for searching the registry, but it's up to you.

If you want to feel safer about the actual deletion, use 'Default Programs Editor' - the 'Open With' section.

Steps (I think!):
a. Download and install Default Programs Editor & Regscanner
b. *** Back up the registry - or create a restore point
N.B. System restore is NOT enabled in Win 10 by default, so you must do that first.
(You can research how to do the above easily if you're not sure).
Launch Default Programs Editor & Regscanner
c. search the registry key as above with regscanner
d. For each instance of %1 you don't want, locate it using Default Programs Editor and delete it. (Or if you're confident, just edit the registry).

You can find the two programs easily by searching for
"Default Programs Editor"
(with "") and
Regscanner

- more for background

 

Thank you for explanation in wide. I fixed it. Problem was program incompatibility with win10, so win pull %1 instead of program name etc.
