How to Change File Associations in Windows 10

Many people have different programs on their PC’s that can open the same type of file. For example, you may have 2 different programs have the ability to open/view/edit PDF files. Some of you may prefer one or the other, but for some reason, Windows decides to always use the program that you do not prefer to open the file.  This Tech Tip will cover Windows 10 file Associations, and how to associate a particular program with a file type or extension.

A common error we find people encountering is when an icon is blank.  When you see this, the common cause is there is no program associated to the file type.
