How to Set VLC, PotPlayer, or Any Custom Video Player as Default in Windows 11

If you watch a lot of videos on your PC, you’ve probably noticed that Windows 11 opens them with the built-in Movies & TV or the new Media Player app by default. Those apps are fine for quick viewing, but many people prefer feature-packed players like VLC, PotPlayer, or others. The good news is that it’s easy to make your favorite video player the default in Windows 11, so every video opens exactly where you want it to—no extra clicks required.

Why Use VLC, PotPlayer, or Another Player Instead of the Built‑In App?

Windows’ own video app is designed to be simple, but that simplicity can feel limiting once you start exploring other options. Third-party players like VLC Media Player and PotPlayer are popular for a reason: they give you more control, better compatibility, and a smoother viewing experience, especially if you watch a variety of formats or higher-quality content.

One of the biggest advantages is format support. VLC, for example, is famous for playing “almost anything” out of the box—.mp4, .mkv, .avi, .mov, and many more obscure formats. If you’ve ever double-clicked a file only to see an error or hear audio with no video, switching to a more capable player can fix that frustration instantly. PotPlayer is also known for handling a wide range of codecs and high-resolution files with ease, which is great if you watch 4K, HDR, or large Blu‑ray rips.

These players also shine when it comes to advanced features. You get options like precise playback speed control, powerful subtitle handling, audio and video filters, screenshot tools, playlist management, and even streaming from network sources. If you’re watching foreign films, anime, or lecture recordings, the ability to tweak subtitles, jump back a few seconds, or fine‑tune audio sync makes a huge difference in comfort and enjoyment.

Finally, there’s the simple factor of personal preference. Maybe you like VLC’s straightforward interface, or you enjoy PotPlayer’s detailed settings and keyboard shortcuts. Once you’ve found a player that feels right, setting it as the default keeps your workflow smooth: every double‑click launches the app you actually want, instead of something you immediately close.

How to Set a Custom Video Player as Default in Windows 11

Before you change anything, make sure your preferred video player—like VLC or PotPlayer—is already installed. Once that’s done, you can update your defaults through the Windows 11 Settings app. It sounds a bit technical, but if you follow the steps carefully, it’s very straightforward.

1. Click the Start button and choose Settings, or press Windows key + I on your keyboard.
2. In the left‑hand sidebar, click Apps.
3. Click Default apps. This is where Windows manages which programs open different types of files.
4. At the top, you’ll see a search box labeled Set defaults for applications. Type the name of your player, such as VLC or PotPlayer.
5. Click your player in the results. You’ll now see a list of file types and link types that can be associated with it.

This list might look a little overwhelming, but you really only need to focus on the common video formats you actually use. For most people, that means .mp4, .mkv, .avi, .mov, and possibly .wmv or .flv if you have older files. For each one, you’ll see the current default app listed to the right.

6. Click a file type, for example .mp4. A small window will pop up showing apps that can open that format.
7. Select VLC media player, PotPlayer, or whichever player you prefer, then click OK or Set default.
8. Repeat this for other formats you use, like .mkv, .avi, and .mov, until they all show your chosen player as the default.

Once you’ve done this, double‑clicking any of those video files in File Explorer will automatically open them in your custom player. No more right‑clicking, no more “Open with” menus—just instant playback with the app you actually like using.

Assigning by App vs. Assigning by File Type: What’s the Difference?

When you’re in the Default apps section, Windows 11 lets you think about defaults in two ways: by app and by file type. It’s easy to blur the two, so let’s quickly clear it up in friendly, everyday terms.

Assigning by app is what you did when you searched for VLC or PotPlayer and opened their default settings page. You’re basically telling Windows, “Here’s this app—what kinds of files should it handle?” You then go through the list and flip specific formats over to that player. It’s a convenient way to see everything one app could open and choose what you want it to handle.

Assigning by file type works from the opposite direction. Instead of starting with the app, you start with the extension. Still in Settings → Apps → Default apps, scroll down a bit and you’ll see a section where you can search by file type. If you type .mp4 there, you’ll see which app is currently set as the default for MP4 videos and can change it to another one. This is handy if you only want to switch one or two specific formats without touching anything else.

In practice, both paths lead to the same place: every file type ends up with a single default app. Choosing by app is great when you’ve just installed a new player and want it to handle most of your videos. Choosing by file type is perfect when you’re fine‑tuning, like deciding you want VLC for movies but a lighter player for quick clips, or keeping one tool just for rare formats.

A Quick Alternative: Right‑Click a Video and Use “Open With”

Sometimes you don’t want to dive into Settings at all—you just want this one video to open in a different player. Windows 11 gives you a simple shortcut for that through the right‑click menu, and you can even use it to change the default on the fly if you decide you like the new behavior.

In File Explorer, right‑click any video file, such as an .mp4. Hover over Open with, then either pick your player from the small list or click Choose another app if you don’t see it right away. In the window that appears, select your preferred player and, if you want to make it the new default for that file type, check the box that says something like Always use this app to open .mp4 files. Click OK, and from then on, that format will open in your chosen player automatically.

This right‑click method is especially friendly if you’re experimenting. You can try a new player for a few files, see how it feels, and only commit to making it the default when you’re sure it fits your viewing habits. With just a couple of clicks, Windows 11 will happily follow your lead and send your videos to the app that makes them look and sound their best.
