Last week (09/29/2018) I was screwing around trying to fix a driver issue I was having on my Windows 7 install, long story short I screwed something up and could no longer get the OS to load. So I figured hey if I have to reinstall Windows might as well install 10. So I wiped out the by drivers partitions and started to do a completely fresh install of Windows 10. Fast forward to today(10/03/2018) and I have figured out fixes for most of my major annoyances with Windows 10 but one. I CANNOT change file type associations using ANY method built into the operating system.
Windows 10 Pro x64 Build1803
Local account only
How I have tried to set the application to be used...
1) "Right Click" on file > Open With... > Choose Another App > Find and select app and check "Always use this app" > Ok
2) "Right Click" on file > Properties > Change... > Find and select app > Ok > Apply
3) Settings (Windows Key + i) > apps > default apps > Choose default apps by file type > Find file type > Pick app from list
4) Settings (Windows Key + i) > apps > default apps > Set defaults by app > Find app and click manage > No actual option to add the file type
What I have tried to fix the problem...
1) Deployment Image Servicing and Management
2) System File Checker
3) Control Panel Classic (Well couldn't actually try it as MS has removed those pages)
4) Deleting any MS Account info stored on the computer (Account used to sign into the MS app store)
As a temp workaround I have found some 3rd party applications that can do what Windows seemingly cannot do so its not all doom and gloom, but it is rather depressing that this is an issue to begin with.
So, Any thoughts on how to go about fixing this?
UPDATE1: I noticed in task manager that after every attempt to set an application to use, a new instance of "OpenWith.exe" starts up and persists until I terminate the process or logout/restart/shutdown.
UPDATE2: For those that find this and are at least looking for temporary workarounds...
2) Default Programs Editior
UPDATE3: Another application workaround
Total Commander - an alternative to File Explorer
UPDATE4: For my use cases this issue has been resolved after installing the following update
