Windows 10 version 2004, which was released on May 27, is
currently available for seekers or those who manually check for
updates in Windows Updates settings.
In addition to new features, Windows 10 version 2004 (May 2020
Update) also comes with
improvements to block potentially unwanted programs, also
known short PUPs and PUAs, from showing up on your system or
being installed on Windows PCs.
Windows 10 May 2020 Update allows you to maintain a track of
the potentially unwanted programs and prevent them from being
downloaded or installed on Windows 10 systems.
According to Microsoft, the Potentially Unwanted Programs or
Potential Unwanted Programs come included in various types of
software bundling and driver or registry optimizer.
After applying May 2020 Update, users are reporting that Windows
Security app triggers security threat alerts even when the PUA
file is gone. After the PUA has been removed or allowed to run
on Windows 10, later scans of Windows Security are detecting
the old items again, causing an erroneous detection loop.
“I was doing my routine scan and I found these threats
highlighted as low and Defender wasn’t able to remove them,
they keep showing up. I scanned using Malwarebytes as well, but
this doesn’t show up over there,” one user noted.
It appears that Windows Defender has been defaulted to identify
PUPs as a threat in Windows 10 version 2004. After the PUP has
been removed, Windows Defender identities the same file again
and again as a threat on the subsequent scans of the history.
To fix PUP and PUA warnings in Windows Security app, you would
need to delete PUPs history information by following these
- Open File Explorer.
- Navigate to C:Program DataMicrosoftWindows
- In the Service folder, delete PUP related files.
- Restart Windows and do a quick scan in Windows Security
The notifications for PUPs won’t show up again unless another
PUP file is loaded on your system.
It’s not yet clear whether Microsoft is aware of the reports,
but a fix could be on the horizon as the issue has been widely
reported by affected users on Microsoft’s answers forum.
