What are File Associations?

File associations are what tells Windows to open a specific program when you double-click on a file to open it.  If there is no file association set in Windows then you will be given a dialog to set one.  Also, when you install programs if that program uses the file extension it may set the file extension to open when you try to open that file.  But what if you set the wrong one or want to chat what program opens.  Let’s hop into how to remove default file association in Windows 10 using the Windows Registry.
