One of the latest additions to Windows Defender Antivirus' arsenal of protection tools blocks potentially unwanted programs, short PUPs, from landing on the system or being installed on Windows PCs.

Note: Potentially Unwanted Programs (PUPs) and Potentially Unwanted Applications (PUAs) refer to the same type of potentially unwanted software.

Microsoft improved the defensive capabilities of the built-in antivirus and security tool Windows Defender significantly for Windows 10.

The company added features such as Windows Defender System Guard and Application Guard, Network protection, Controlled Folder Access, or Exploit protection in recent years to the tool. Microsoft even published Windows Defender Browser Protection for Google Chrome.

Some features are reserved for Enterprise editions of Windows 10 but some are also available in Home editions.

Enable the potentially unwanted programs protection in Windows Defender


Open Windows PowerShell with Windows-X and the selection of Windows PowerShell (Admin) from the context menu.

If you don't see Windows PowerShell (Admin) listed there do the following instead: open Start, type Windows PowerShell, right-click on the result, and select "run as administrator".
- Confirm the UAC prompt that is displayed.
- The console that opens should being with "Administrator".
- Type "Set-MpPreference -PUAProtection Enabled" and hit the Return-key.
