Change Default Programs for Extensions in Windows

Read this complete article to change default programs for extensions in Windows. When I click on a video file on my laptop having extension like, mp4, avi, mkv, etc., VLC Media Player opens it by default. If I click on audio file type like, mp4, wav, aac, etc,  Windows Media Player opens it by default. These file types have the extensions which are associated to specific programs in windows to handle them by default. The question is, how to change default programs for extensions in windows? There are multiple ways to do this. Let’s see them one by one.

Change Default Programs for Extensions in Windows: Properties

If you want to change the default program for specific extension, there is one simple method for this. Let me explain this with example. I have a video on my laptop with AVI extension. As I said before, if I click this video file, VLC Media Player opens it by default. Now I want Windows Media Player to open this file by default. That mean I want to change the default program of AVI extension.

To change the default program for specific extension, right click on extension file and select Properties. In “Properties” window, in “General” section, we should change “Opens with:”. Click “Change” and there will be “Recommended Programs”, if the program you want is not listed there, look it into “Other Programs” list. Select the program that you want to make default for that specific extension and click “Ok”. Then click “Ok” in Properties window to save your changes. Next time when you will click on the file with that type of extension, it should open with the program that you selected as default for that extension.

If the program that you want to make as default is not listed in both “Recommended Programs” and “Other Programs” lists, then you have to add it manually. In “Properties”, you clicked “Change” for the option “Opens with:”. Now as your program is not listed in both lists, click “Browse”. Go where the program files of that Program are saved. Generally these files are saved into Program files folder in C Drive. In Program Files folder, look for the folder of your Program. Select the application file in this program folder, the file that opens the program. Sometimes, it is with .exe extension. Once selected, it will get added into “Recommended Programs” list. Click Ok and save your changes. Next time the files with that extension should open with the program that you just added.
