How to Enable or Disable SmartScreen for Microsoft Store Apps on Windows 11
Microsoft Defender SmartScreen for Microsoft Store apps helps protect you by checking apps before you run them.
SmartScreen acts like a security guard for apps you get from the Microsoft Store. It stops you from opening anything that looks dangerous.
On Windows 11, this feature is on by default to keep your PC safer. It checks apps against a list of known threats.
You can choose to turn SmartScreen on or off in your Windows 11 settings to control how strictly these Store apps are checked.
Open Windows Security, navigate to App & browser control, then Reputation-based protection settings. Locate SmartScreen for Microsoft Store apps and toggle the switch to On or Off.
How SmartScreen Works
Microsoft Defender SmartScreen checks apps and websites for safety before you use them. This protection helps prevent you from opening potentially harmful software or visiting malicious websites.
Managing SmartScreen for Microsoft Store Apps
You can manage Microsoft Defender SmartScreen settings for apps downloaded from the Microsoft Store directly in Windows Security. This feature helps protect your PC by checking apps from the Store for potential risks, and you can choose to turn it on or off based on your preferences.
- In the search box on your taskbar, type Windows Security and click on Windows Security.
- Click on the App & browser control tile.
- On the next page, look for Reputation-based protection and click the Reputation-based protection settings link.
- Find the section labeled SmartScreen for Microsoft Store apps. Toggle the switch to On or Off based on your preference.
Enterprise Management via Group Policy
IT administrators (often called IT admins) use the Group Policy Editor to manage Microsoft Defender SmartScreen settings across many computers at once, helping to ensure that all devices adhere to the same security standards.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
You can set the EnableSmartScreen value to 1 to enable or 0 to disable it.
Troubleshooting and False Positives
If Microsoft Defender SmartScreen incorrectly flags a safe app as dangerous, it’s called a false positive. You can report it to Microsoft.
Summary
Microsoft Defender SmartScreen is a security feature that helps protect your Windows computer by checking apps and websites for safety.
What does it mean when I see the ‘site reported as unsafe’ warning?
This warning means Microsoft Defender SmartScreen has identified the website as a potential source of phishing or malware. It is highly recommended that you do not proceed to the site, as it may attempt to steal your personal information or install harmful software on your computer.
Does SmartScreen affect system performance?
SmartScreen has a minimal impact on system performance. It performs checks in the background using cloud-based threat intelligence. Most users will not notice any slowdowns while browsing or downloading apps, as the security benefits far outweigh the negligible resource usage required for these safety checks.
