By default, Windows 11 is designed to prioritize apps from the Microsoft Store for better security and reliability. But what if you want to install apps from outside sources — like software from official websites or trusted third-party developers? That’s where knowing how to allow non-Microsoft apps on Windows 11 becomes essential.
In this guide, we’ll explain why Windows blocks certain apps by default, the risks of allowing non-Microsoft apps, and a step-by-step guide to enabling them safely.
📝 Quick Summary (Key Takeaways)
-
By default, Windows 11 restricts installations to Microsoft Store apps for security.
-
You can change this in Settings → Apps → Advanced app settings.
-
Options include: “The Microsoft Store only,” “Anywhere,” or “Anywhere, but let me know if there’s a comparable app in the Microsoft Store.”
-
Allowing non-Microsoft apps gives you more flexibility, but you should only download software from trusted sources to avoid malware.
Why Does Windows 11 Block Non-Microsoft Apps by Default?
Windows 11 prioritizes Microsoft Store apps because:
-
✅ Security: Store apps are vetted for malware and harmful behavior.
-
✅ Reliability: They follow Microsoft’s compatibility standards.
-
✅ Stability: Reduces chances of corrupted installations or system crashes.
This doesn’t mean non-Microsoft apps are unsafe — many legitimate apps like Google Chrome, Zoom, and Adobe Reader are distributed outside the Microsoft Store.
How to Allow Non-Microsoft Apps on Windows 11 (Step-by-Step)
Here’s the exact process to enable third-party apps on your Windows 11 PC.
Step 1: Open Windows Settings
-
Press Win + I on your keyboard.
-
Or click the Start Menu → Settings.
Step 2: Navigate to App Settings
-
In Settings, select Apps from the left-hand sidebar.
-
Click on Advanced app settings (under Apps).
Step 3: Change “Choose Where to Get Apps” Option
-
Under Choose where to get apps, you’ll see options like:
-
The Microsoft Store only (default for stricter security).
-
Anywhere, but warn me before installing an app that’s not from the Store.
-
Anywhere, but let me know if there’s a comparable app in the Microsoft Store.
-
Anywhere (allows all third-party apps without warnings).
-
-
Select Anywhere or one of the more flexible options depending on your comfort level.
Step 4: Confirm and Install Your App
-
Once enabled, you can install non-Microsoft apps by simply downloading the installer (usually .exe or .msi) from the app’s official website.
-
Double-click the file to run the setup.
-
If Windows asks for confirmation via User Account Control (UAC), click Yes to proceed.
Alternative Method: Using Sideloading for Apps
If you’re trying to install Android apps or sideload packages, follow these steps:
-
Go to Settings → Privacy & Security → For developers.
-
Enable Install apps from any source, including loose files (developer mode).
-
Confirm the warning message and proceed.
