Windows 10 May 2020 mega update to get PUA (potentially unwanted applications) blocking feature


Windows 10 May 2020 mega-update will bring PUA/PUP protection feature to Windows 10 PCs and Laptops

Microsoft engineers are burning the night oil to release the Windows 10 May 2020 before May ends. From the looks of it, the due date of 26th May is likely to be extended further due to the fact that the engineers are struggling to find a patch for the DISM zero-day vulnerability. That being said, the Windows 10 May 2020 mega-update will bring many new features to the Windows 10 users. One of them is the ability to enable/disable installation of known PUAs (potentially unwanted applications) or PUPs (potentially unwanted programs).

The May 2020 update of the Windows 10 operating system will now include a new security feature that can detect and block the installation of known PUAs (potentially unwanted applications), Microsoft announced on Tuesday. The PUAs are also called PUPs (potentially unwanted programs) in security geek language.

After downloading the Windows 10 May 2020 mega-update (when it comes), Windows 10 users can enable/disable the feature that allows the PC/laptop to install potentially unwanted Apps and software. Windows 10 will now flag bundled software which contain malicious Apps and silent installs to bypassing user consent if you enable the disable the PUP feature. The feature will work basically like Android smartphone’s install from unknown sources feature which an Android smartphone owner can toggle on and off.

Microsoft described the PUAs as apps that show intrusive ads, apps that track users and sell their data to advertisers, apps that change browser settings, install root certificates, or disable security controls. Right now Windows 10 allows users to block unrecognized Apps and software flagged by Windows Defender. In the new update, the blocking will be done natively by Windows 10 system itself.

The feature is turned off by default, so users will have to manually enable it once they update to Windows 10 May 2020 (v2004).

This can be done by going to

Start > Settings > Update & Security > Windows Security > App & browser control > Reputation-based protection settings.

Once enabled, users will be offered two options. You can do well to enable both.

  • Block downloads looks for PUA as it’s being downloaded, but note that it only works with the new Microsoft Edge browser.
  • Block apps will detect PUA that you’ve already downloaded or installed, so if you’re using a different browser Windows Security can still detect PUA after you’ve downloaded it.

It remains to be seen what users can do with falsely flagged Apps and software through this feature.
