Enabling Non-Microsoft Applications on Windows 11: A Complete Tutorial

Enabling Installation of Non-Microsoft Apps on Windows 11

Windows 11 can feel a bit locked down when it comes to installing apps, can’t it? If you want to run software outside of the Microsoft Store, here’s how you can do it. Once you’ve set this up, you’ll have more flexibility to try out apps that aren’t available in the Store. Let’s get started.

Opening Settings

First, click on the Start menu in the bottom-left corner and select the gear icon for Settings. This is your go-to place for tweaking Windows. You can also press Windows + I as a shortcut.

Finding the Apps Section

Next, head over to the Apps section. That’s where all your installed software sits, and you’ll need to make some changes here. Alternatively, right-click the Start button and select Apps & Features to get there faster if you’re already familiar with it.

Accessing Apps & Features

In the Apps menu, click on Apps & features. This is the spot where you decide what apps you can install. It’s important because it tells Windows what sources to trust. If you prefer, you can also search for “Apps & features” in the Settings search bar.

Changing the App Source Setting

Here’s the important part: look for the dropdown labelled Choose where to get apps (sometimes called Set the install source). It might currently be set to only allow installing from the Microsoft Store. Change it to Anywhere — this will enable you to install apps from websites or other third-party sources. Sometimes, you might find this option under Settings > Apps > Advanced app settings > Install apps from anywhere. And yes, Windows may display a couple of sentences about enabling sideloading—that’s how it says you can install apps from outside the Store.

A quick note: on certain editions of Windows 11, the wording might be “Allow apps from anywhere,” often accompanied by a prompt to confirm sideloading. Just keep that in mind.

Confirming Your Settings

After making the change, you might see a security warning about installing unverified apps. It’s a warning, not a showstopper — if you trust the source, click Accept. Your system will then be ready to run third-party apps. To double-check, go to Settings > Privacy & Security > Windows Security > Application & browser control to ensure the Reputation-based protection is set to your preference for external software.

Tips for Staying Safe While Installing Non-Store Apps

Expanding your app options is great, but it pays to be cautious. Always download software from trusted sources. Keeping your antivirus software up to date is a good habit. Pay attention to app permissions during installation—sometimes they give you a good idea of what the app will do. Regularly removing apps you no longer use can help keep your system running smoothly. And don’t forget to back up important files before installing new software, just in case something doesn’t go as planned. Running Windows Defender or another trusted security tool is always a solid backup layer of protection.

Common Questions About Changing App Source Settings

Can I switch back to only installing apps from the Microsoft Store?

Absolutely. Just revisit that dropdown and set it back to “Microsoft Store only.” It might feel safer, and it’ll limit what can be installed, but you won’t have to worry about questionable apps anymore.

Is allowing non-Microsoft apps risky?

There is some risk, naturally. Not all third-party apps are reliable, so be extra careful about where you get them. Turning on SmartScreen in Windows Security can help block shady downloads.

Will this slow down my PC?

Not typically. Changing this setting shouldn’t affect your system’s performance. However, installing lots of hefty programs could impact speed, especially on older hardware.

Does this interfere with Windows updates?

Nope. Your Windows updates will keep coming through normally, regardless of your app installation preferences.

Do I need to restart my computer after changing these settings?

No, a restart isn’t usually necessary. The changes take effect immediately. Sometimes, you might need to restart Windows Explorer via Task Manager to see the full effect, but that’s rare.

Wrapping It Up

Allowing installation of third-party apps on Windows 11 opens up a lot of new possibilities for software and tools. If you’re a developer, tech enthusiast, or just someone who likes to customise their PC, it’s a handy feature. Just remember to stay cautious about what you install and keep your security measures up to date. For newcomers, sticking with well-known sources while you learn the ropes might be the safest bet.

Quick checklist:

  • Open Settings (Windows + I).
  • Go to Apps > Apps & features.
  • Set app source to Anywhere.
  • Proceed and accept any security prompts.

Hopefully, this guide helps save you some hassle — good luck and happy tinkering!
