How to Change Default Apps in Windows 11: A Step-by-Step Guide

Windows 11 comes with a set of default applications that open your files, emails, web pages, and more.

But what if in a small business environment you prefer a different browser, email client, or media player?

Changing these defaults can streamline your workflow and make your computer feel truly yours.

This guide walks you through every step to customise default apps in Windows 11, ensuring your favorite programs take center stage.

Why Changing Default Apps Matters For Small Business Owners

Default apps determine which program launches when you open a file or perform a specific action.

For example, clicking a .jpg file might open the Photos app by default, but you might prefer Adobe Photoshop or another image viewer.

Similarly, the default web browser might be Microsoft Edge, but many users opt for Chrome, Firefox, or Brave.

Having control over default apps means faster access to tools you trust, better integration with your workflow, and often improved performance.

It also helps avoid frustration when files open in apps you don’t like or don’t use and as a small business owner time is of essence.

Moreover, the choice of default applications can significantly influence your productivity within your small business environment.

For instance, if you regularly collaborate on documents, setting Google Docs or Microsoft Word as your default word processor can streamline your workflow, allowing for seamless sharing and editing.

This is particularly important in professional environments where time is of the essence, and efficiency can make a substantial difference in project outcomes.

Additionally, customizing your default apps can enhance your overall user experience, as it allows you to tailor your digital environment to your specific needs and preferences.

Furthermore, the implications of default apps extend beyond mere convenience; they can also affect security and privacy.

For example, opting for a browser that prioritises user privacy over one that collects data can help safeguard your personal information.

Similarly, choosing a media player that supports a wide range of formats can protect you from potential vulnerabilities associated with less secure applications.

By thoughtfully selecting your default apps, you not only create a more personalized computing experience but also take proactive steps toward enhancing your digital security.

Where to Find Default App Settings in Windows 11

Windows 11 has revamped its Settings interface, making it more user-friendly but slightly different from Windows 10. To change default apps, you'll need to navigate through the Settings app.

Accessing Default Apps Settings For Your Small Business Computer

Start by clicking the Start button or pressing the Windows key, then select the gear icon labeled “Settings.”

Alternatively, press Windows + I to open Settings directly.

From the Settings window, click on Apps in the left sidebar. Then, select Default apps from the list.

This is where you’ll manage all your default programs.

Within the Default apps section, you’ll find a comprehensive list of file types and protocols, each associated with a specific application.

For instance, if you want to change the default program for opening PDF files, simply scroll down to the .pdf entry and click on it.

A list of compatible applications will appear, allowing you to select your preferred PDF viewer.

This flexibility makes it easy to customize your experience according to your preferences.

Moreover, Windows 11 introduces a more intuitive search function within the Default apps settings.

Instead of scrolling through the entire list, you can type the name of the application or file type you wish to change in the search bar at the top.

This feature streamlines the process, especially for users who frequently switch between different applications for various tasks.

It’s a small but significant enhancement that reflects Microsoft’s commitment to improving user experience in its latest operating system.

Changing Default Apps by File Type or Protocol

Windows 11 allows you to set defaults in two main ways: by file type (like .pdf or .mp3) or by protocol (like HTTP or MAILTO).

This granular control ensures you can customize exactly how your system behaves.

Setting Defaults by File Type

Within the Default apps section, scroll down to the Set defaults for file types or link types area.

Click on the link labeled Choose defaults by file type.

You’ll see a long list of file extensions and the apps currently set to open them.

To change the default app for a specific file type, scroll or search for the extension (for example, .pdf).

Click the current default app shown next to it.

A pop-up will appear with a list of installed apps capable of opening that file type. Select your preferred app, then click OK.

For instance, if you want PDFs to open in Adobe Acrobat instead of Microsoft Edge, find .pdf in the list and change it accordingly.

Setting Defaults by Protocol

Protocols are how Windows handles certain types of links or actions, like web addresses (HTTP, HTTPS) or email links (MAILTO).

To change defaults by protocol, go back to the Default apps page and click Choose defaults by link type.

Find the protocol you want to change, such as HTTP or MAILTO, and click the app listed next to it.

Choose your preferred app from the list. For example, you might want to open HTTP and HTTPS links in Firefox instead of Edge.

Changing Default Apps by Application

Another way to set defaults is by choosing an app and specifying which file types or protocols it should open.

This is useful if you want one app to handle all relevant files.

How to Set Defaults for a Specific App

In the Default apps section, use the search bar under “Set defaults for applications” to find the app you want to set as default. Click on the app’s name.

You’ll see a list of file types and protocols that the app can open, along with the current default app for each.

Click on the file type or protocol you want to change, then select the desired app from the pop-up.

This method is handy if you just installed a new app and want to quickly assign it as the default for everything it supports.

Changing Default Apps for Common File Types

Some file types and protocols are more commonly customised than others. Here’s how to change defaults for some popular categories.

Web Browser

By default, Windows 11 uses Microsoft Edge as the web browser. To switch to Chrome, Firefox, or another browser, you need to change defaults for several protocols and file types:

• HTTP and HTTPS protocols: These control web links.
• .htm and .html files: These are web page files.
• .pdf files (optional): Some browsers also open PDFs.

Change each of these to your preferred browser to ensure all web-related content opens correctly.

Email Client

Windows 11 defaults to the Mail app for email links. To use Outlook, Thunderbird, or another email client, change the default app for the MAILTO protocol.

Search for MAILTO in the protocol list and select your preferred email program.

Music and Video Players

Windows Media Player and the Movies & TV app are the defaults for many audio and video files.

You can switch these to VLC, Spotify, or another media player by changing defaults for file types like .mp3, .wav, .mp4, .avi, and others.

Set defaults by file type or by the app to cover all relevant formats.

Tips for Troubleshooting Default App Changes Affecting Small Business Owners

Sometimes, changes don’t stick or apps don’t appear as options. Here are some tips to resolve common issues:

Make Sure the App Is Installed

If your preferred app doesn’t show up in the list, double-check it’s installed correctly.

Some apps need to be installed from the Microsoft Store to appear in default app lists, though many desktop apps will show up as well.

Update Windows 11 For Your Small Business Environment

Keeping Windows updated ensures you have the latest fixes and features. Sometimes, bugs related to default apps are resolved in updates.

Reset Default Apps

If things get messy, you can reset all default apps to Microsoft’s recommended defaults. In the Default apps section, there’s a button labeled Reset under “Reset to the Microsoft recommended defaults.” Use this to start fresh.

Use “Open With” to Set Defaults Quickly

Right-click any file, select Open with, then Choose another app. Check the box labeled Always use this app to open .[file extension] and select your preferred app.

This method sets the default for that file type instantly.

Changing Default Apps via Control Panel and Registry

Windows 11 encourages using the Settings app for default apps, but some advanced users might want to use legacy tools or make registry edits.

Using Control Panel

Open Control Panel and navigate to Programs > Default Programs > Set your default programs. Select the app and click Set this program as default. This sets the app to handle all file types and protocols it supports.

This method is less granular than Settings but still effective.

‍

Changing default apps in Windows 11 is straightforward once you know where to look.

Whether you want a different browser, email client, or media player, the Settings app gives you full control.

Remember to change defaults for all relevant file types and protocols to avoid surprises.

Customising your defaults makes your PC feel more personal and efficient. Take a few minutes to set it up the way you like-it’s worth it.
