step 1: open up word and make a new document. You can just write whatever on it, doesn't really matter.

step 2: save the document you just made to where you can easily find it.

step 3:copy the document you just made and then rename it to a "fake" file type. i just put .mmm at mine. then move the dummy file to a separate folder, so its easier to find later

step 4: right click the file you'd wish to remove the default for, hover over open with, mark the checkbox that says always use this app and then select choose another app.

step 5: locate the dummy file you just made. you'll have to select all file types to find it. then select the dummy file and press ok. windows will say that the app cant open the file type, but you can just ignore that.



that should just about fix the problem for you

Restore Default File Type Associations in Windows 10  


Not to pester you, but it is inconvenient to "open with" every single time, and I remain quite perplexed why every other possible file extension appears to be listed in "Settings/System/Default apps/CHOOSE DEFAULT APPS BY FILE TYPE" but not .zip. It has always been possible prior to Windows 10 to associate ANY file extension with a default program. I'm not sure what you mean by ".zip is not listed by default." How else would one permanently associate a program with a file extension? The link I gave you, provided again below, as well as others I could find - indicates that that other people have .zip listed in their file type listings. Have you checked your listings available at location I've specified above? I have ... .yps, .z, .z96... and no .zip. Do you not see a .zip extension either but see essentially all others?

How to remove a default file association app from a file type in Windows 10

Could Microsoft please answer the question, how do you remove a file association ?

I inadvertently associated a file with Adobe DC and now cannot remove it. Tried uninstalling Adobe and that did not work. In the file association list the file with extension .ica (the one a wrongly linked to Adobe) just has a blue box beside it, not the
standard + showing that no association has been made. When I try to pen the file it is looking for the original path of the Adobe program. so It still cannot remove the association. Any one fixed this yet ? Maybe needs a change to the registry.

 

How to remove a default file association app from a file type in Windows 10

I have searched all over and I don't think there is a way to do that, but doing what Steve suggested worked for me.

Once you delete the bogus file, when you try to open that other file, it will ask you what to open it with since the bogus file you associated the file type with is no longer there. I think that might be what some are forgetting to do: delete the bogus
file after you associate your file type with it.

Here's what he posted.

• Right click your desktop and create a new file such as Notepad, Bitmap... quite literally anything except shortcut and folder.
• When naming the file name it something abnormal thats not already associated (i.e named mine Test.testdog)
• Go back to the file that accidentally associated and right click the file and choose to open with->Choose another app, ensure the checkbox is selected to always associate and scroll down to the bottom to browse for "Look for another app on
  this PC".
• Navigate to your Desktop (or wherever you saved the file) and ensure the box at the bottom right is changed to "Show all files" you show now see the file you made, simply choose it and hit OK.
• This will prompt and error, click out of it, you should now notice the file associate is now unassociated.

Hope this helps someone!
