Trying to install a third-party app on Windows 11 and hitting a wall with restrictions? You’re not alone. By default, Windows 11 prefers apps from the Microsoft Store to keep your system secure, but this can sometimes be limiting—especially if you trust an app from another source.
In this guide, we’ll show you how to allow third-party apps on Windows 11 easily and safely.
Why Are Third-Party Apps Blocked by Default?
Microsoft designed Windows 11 with tighter security to prevent malware and suspicious apps from sneaking in. By default, it restricts installations to apps from the Microsoft Store, as these are verified and more secure.
However, many legitimate apps are not listed in the Store, and you might need to override this restriction.
Is It Safe to Allow Third-Party Apps?
Yes—if you know what you’re downloading and trust the source. But be cautious: installing apps from unknown sites can expose your system to security risks.
Steps to Allow Third-Party Apps on Windows 11
Here’s how to adjust your system settings to install apps from outside the Microsoft Store.
Open Settings
- Press Win + I to open the Settings app.
- Go to Apps from the left-hand menu.
Access Advanced App Settings
- Click on Advanced app settings.
- Select Choose where to get apps.
Change Installation Preference
- In the dropdown, select Anywhere.
- You may also see:
- Anywhere, but let me know if there’s a comparable app in the Microsoft Store
- The Microsoft Store only (recommended)
Choose the first option for full flexibility.
Install the Third-Party App
- Download your desired app from a trusted source.
- Run the installer file (.exe or .msi).
- Follow the on-screen instructions to complete the installation.
Allowing Apps via SmartScreen Settings
Sometimes, Windows SmartScreen blocks an app even after changing app installation preferences.
- Right-click the app’s installer.
- Select Properties.
- Under the General tab, check Unblock (if available).
- Click Apply and OK, then install the app.
Temporarily Disabling SmartScreen for App Installation
If the above doesn’t work:
- Go to Settings > Privacy & Security > Windows Security.
- Click App & browser control.
- Under Check apps and files, choose Warn or Off temporarily.
- Install the app, then turn SmartScreen back on for safety.
Best Practices for Installing Third-Party Apps
- Always download from official websites or trusted sources.
- Avoid pirated software—it often contains malware.
- Scan the file with Windows Defender before installing.
- Keep your system and antivirus up to date.
Will Allowing Third-Party Apps Void My Warranty?
No, it won’t void your warranty or license. However, if the app damages your system, Microsoft isn’t responsible for those issues.
How to Revert the Settings
If you want to return to the default (Microsoft Store only):
- Go back to Settings > Apps > Advanced app settings.
- Change the option to The Microsoft Store only.
Conclusion
Allowing third-party apps on Windows 11 gives you more freedom and flexibility, but with that comes responsibility. Always ensure your sources are trustworthy, and enable the restriction again if you don’t plan on installing more apps soon.
