Many types of files can be opened by more than one program. For example, you can open a photo with the Photos program or with Paint, among others. Follow these steps to change the default program that Windows uses to open each type of file.
Adjust file type associations
Each file in your Windows operating system has an extension in its filename, eg. .txt, .doc, etc. These extensions are used to identify the program, with which, windows can open this file. You can set or change these file associations in your Windows 11 or Windows 10 OS.

If you've ever run into the problem of Windows trying to open up a file in entirely the wrong application, you're not alone. Although you can get around it using the "Open With" command, there is a way to make sure you don't have to do that every time: Learn how to change file associations.
Step 7: Choose your preferred application from the list that appears and click its corresponding icon. In the case of some file types, there will be multiple options, whereas others may have none.
You'll only see this link if you're on the Category or Control Panel Home view of Control Panel. Otherwise, choose Default Programs instead, followed by Associate a file type or protocol with a program link. Skip to Step 4.
The most common programs that support this particular file type will be listed under the Recommended Programs or Programs list, but there may be other programs that support the file as well, in which case you can manually select one with the Browse button.
Microsoft uses file associations to set default programs for opening different file types on all its operating systems. As a result, when you open a file, be it text, image, or document, on your Windows PC, it automatically opens that file in a compatible program.
Windows 10 Settings offers a more granular way of managing file associations on your PC. It presents you with all the different file types in use so you can change their default programs with ease. Moreover, you also get the ability to change the default apps for email, music, maps, and web browsing, among others.
With this method, you can also choose the Choose default apps by protocol and Set defaults by app options in step 2. While the former allows you to choose the default program for actions or links, the latter lets you manage an entire program (associated file types and protocols).
To view file associations in Windows 10, open File Explorer and navigate to the folder that contains files of the file type you want to modify. Next, right-click on a file and select Properties from the menu. In the Properties window, check the values against the Type of file and Opens with fields.
Alternatively, go to Settings (Windows + I) > Apps > Default apps. Here, tap on Choose default apps by file type to view the entire list of file type associations on your Windows 10 PC.
When a program is installed in Windows, if configures itself as the default handler for the types of files it knows how to open. For example, Word will associate itself with .docx files, Excel with .xlsx, and VLC Media Player with .mp4 files.
Windows allows you to change file associations by going into Settings > Apps > Default Apps and selecting at the bottom the option titled "Choose default apps by file type".
Rather than having to specify which program you want to use to open a file every time you access it, Windows assigns each file type a default program. These defaults can be changed by the user, or a program could set its own when installed.
Now select the application from the list that you want to use to open the file type of the file you've chosen. If you don't see the program you need, scroll down and select More apps for a wider selection.
Windows 10 has been known to reset default apps by changing file type associations after every update. The best thing you can do to fix this is back up your file type associations and restore them once you discover that a Windows 10 update has messed with them.
You can also go directly into the registry to back up file type associations. However, this is a bit more complicated, and it can sometimes result in a permission error when restoring certain associations. As such, use it as a last resort.
With these methods you'll have full control over your file type associations, ensuring that all your files open in the most suitable program by default. Be wary when installing a new program as some of them will request to become the default program for a set of file types, and you might not want that.
You can set specific file extensions to open in Internet Explorer mode by default using the policy to Set a default associations configuration file. For more information, see Policy CSP - ApplicationDefaults.
5. Click the program thatyou want to use as the default for the file type you selected, or click thearrow next to Other Programs to show additional programs. (Ifyou don't see Other Programs, or your program is not listed,click Browse to find the program you want to use, and thenclick Open. If no other programs are installed that are able toopen the file type or protocol, your choices will be limited.)
