Microsoft will step up the fight against “potentially unwanted software.” The automatic blocking feature of such software will appear in August 2021 in Windows Defender, which ships with the Windows 10 operating system.
Microsoft began blocking Potentially Unwanted Software (PUA) back in 2018. To activate this feature, you had to use PowerShell. But in late spring 2020, the company added the ability to enable it through the Windows Security section.
Automatic blocking of potentially unwanted software will not work on devices with third-party antivirus software installed. But even in Windows Defender, it can be disabled manually. In addition, in the Windows Defender settings, users will be able to see which programs have been blocked.
As for this very “potential unwanted software”, the term refers to torrent clients, operating system optimizers, cryptocurrency mining applications and other software that has a bad reputation.
