Windows 11 is designed with security in mind, which sometimes restricts installing apps from outside the Microsoft Store. While this keeps your PC safer, it can be frustrating if you want to use trusted third-party software. Don’t worry—allowing third-party apps is easy, and this guide will walk you through it step by step.
Why Third-Party Apps Are Restricted
By default, Windows 11 only allows apps from the Microsoft Store to install. This restriction helps:
-
Prevent malware and viruses from entering your system.
-
Ensure app compatibility and reliability.
-
Protect sensitive data on your PC.
However, many trusted developers distribute software outside the Microsoft Store, so you may need to bypass this restriction safely.
Step 1: Open Windows 11 Settings
Start by accessing the system settings:
-
Press Windows + I to open Settings.
-
Click on Apps in the left-hand menu.
-
Select Apps & features.
This is where you control which apps are allowed to install on your PC.
Step 2: Change App Installation Settings
To allow third-party apps:
-
In Apps & features, look for the Choose where to get apps option.
-
Click the drop-down menu.
-
Select Anywhere to allow apps from any source, including the web and other developers.
Tip: Choosing Anywhere, but let me know if there’s a risk adds a safety prompt for extra protection.
Step 3: Confirm the Change
After selecting your preference:
-
A warning may appear, reminding you that installing apps from unknown sources can be risky.
-
Click Yes or Allow to confirm.
Your system now permits third-party apps.
Step 4: Disable SmartScreen (Optional)
Windows 11 has SmartScreen which may block unknown apps. If you trust the app:
-
Press Windows + I → Privacy & Security → Windows Security → App & browser control.
-
Under Check apps and files, select Off.
-
Confirm any prompts.
Warning: Disabling SmartScreen reduces security, so only do this for apps you trust.
Step 5: Install the Third-Party App
Once permissions are adjusted:
-
Download the app from the official website.
-
Run the installer.
-
Follow the on-screen instructions.
The app should install without being blocked by Windows 11.
Step 6: Troubleshooting Common Issues
Sometimes apps still won’t install:
App Blocked by SmartScreen
-
Right-click the installer → Properties → Unblock → Apply.
Administrator Permission Needed
-
Right-click the installer → Run as administrator.
App Compatibility Issues
-
Right-click the installer → Properties → Compatibility tab → Run this program in compatibility mode.
These solutions usually resolve common installation problems.
Step 7: Use Windows Terminal or PowerShell for Advanced Users
Advanced users can allow third-party apps via command line:
-
Open Windows Terminal as Admin.
-
Run the following command:
-
Confirm with Y.
This allows running scripts and installers from trusted third-party sources.
Step 8: Benefits of Allowing Third-Party Apps
-
Access to specialized software not available in Microsoft Store.
-
Greater flexibility and customization for your PC.
-
Ability to use legacy programs or developer tools.
Allowing third-party apps broadens your software options while maintaining control over what’s installed.
Step 9: Stay Safe While Using Third-Party Apps
-
Download from official websites only.
-
Use antivirus software to scan installers.
-
Keep Windows updated to reduce vulnerabilities.
-
Avoid disabling security features for untrusted sources.
These precautions keep your PC secure while enjoying third-party apps.
Step 10: Revert to Microsoft Store Only Apps (Optional)
If you want to tighten security later:
-
Go back to Settings → Apps → Apps & features → Choose where to get apps.
-
Select Microsoft Store only (recommended).
Your PC will return to its default, more secure settings.
Conclusion
Allowing third-party apps on Windows 11 is straightforward once you know the steps. By adjusting app installation settings, optionally managing SmartScreen, and following best security practices, you can safely install trusted software from outside the Microsoft Store. This opens up a world of flexibility and customization while keeping your PC protected.
