Change all File Type Icons By Program

I'm using Photos Legacy in Windows 11, and I've set each individual image file type I use to open with this specific version. All these file types now use the same file icon that Photos Legacy pushed down to them.

Is there a program I can use to change the icon that Photos Legacy uses by default, that will push the new icon down to all these already assigned file types (without having to change/assign the icon for every single file type itself)?

On Windows (recommended: FileTypesMan)
Download FileTypesMan: Download the appropriate version (32/64 bit) from NirSoft and unzip the archive.
Launch the program: Run FileTypesMan.exe (as administrator if necessary).
Find the file type: Find the desired extension (e.g., .pdf, .docx) in the list on the left.
Change the icon: Click the three dots next to "Default Icon", locate the .ico or .exe file containing the new icon, and select it.
Apply: Save the changes.
