Microsoft has begun enabling Windows Defender Potentially Unwanted Application (PUA) protection in Windows 10.

Potentially unwanted applications “may cause your device to run slowly, display unexpected advertisements, or, in the worst case, install other software that may be more harmful or embarrassing,” according to Microsoft. Microsoft points out that these programs are not malware, but are usually software that is not needed or desired.

The company introduced support for PUA blocks in Windows 10 in 2018, but users had to enable the feature using PowerShell; The ability to enable or configure security under the Windows Security Tool was introduced in the May 2020 update for Windows 10. Although it was disabled at the time, users can now configure security under the Windows Security feature on Windows 10 devices.

Protection for potentially unwanted applications will be enabled by default from August 2021, but only for Windows 10 users using Windows Defender and not a third-party protection solution.

Set to block potentially unwanted applications

If you’re using Windows Defender, you can check and configure PUA protection by following these steps:

  • choose Start> Settings.
  • Mene Update and security.
  • choose Windows security.
  • Click the button Open Windows Security.
  • choose Application and browser management.
  • Under the heading Reputation protection, Click Reputation protection settings.
  • Under the heading Potentially unwanted application blocking, if available, select whether you want to block applications and downloads, or just one of the two options.

The same page refers to functionality History of conservation. You can use it to view security measures, including applications or downloads that have been blocked by Windows PUA protection.

Third – party programs such as Configure Defender can also be used to manage security and other Windows Defender features.

Windows Defender is not the only program that can protect you from unwanted programs. Some time ago, Microsoft added PUA protection to its new Edge browser.

Conclusion

Protection against unwanted applications prevents certain programs from being downloaded or installed. Users can still unblock programs to complete the download or installation. False positives are common, just as false positives are common in antivirus solutions, especially when it comes to new programs.

Experienced users may not get the most out of PUA protections, but the same cannot be said for inexperienced users.
