Change file type associations to open files with a new program in Windows 8

The default program to open a certain file type can be changed in Windows 8, simply associate a file type or protocol with another program using the new Control Panel.

What Are File Type Associations?

Windows 8 usually has a default program to open certain file types – the associated file type protocol defines what program is used to open the program automatically. For example, setting the Internet Explorer as your default browser would open all *.HTML files and Links via the Internet Explorer.

This tutorial will teach you how to change any file type associations to open up programs with an application of your choice. Please note that only your user account would be affected and no other user on your PC, so other users would have to do the same
