This post shows students and new users steps to enable or disable Microsoft Defender SmartScreen for Potentially Unwanted Apps in Windows 11. Potentially unwanted applications (PUA) are a category of software that can cause your machine to run slowly, display unexpected ads, or, at worst, install other unwanted spy tools.
When Microsoft Defender SmartScreen is turned on, it can help block PUA apps and files and any attempts to download, run, or install them. In addition, if you try to download a suspicious app, SmartScreen will show you a warning screen, identify the suspected threat, and give you a chance to stop before anything wrong can happen.
These protections are built into Windows and work with Microsoft Defender Endpoint on your device and in the cloud. In addition, Microsoft Security includes additional pIn protection such as Controlled folder access, Real-time protection, Tamper protection, ransomware protection, and Phishing protection.
Below is how to turn off or on Microsoft Defender SmartScreen for Potentially Unwanted Apps blocking in Windows 11
