Microsoft yesterday released a new batch of cumulative updates
for Windows 10 with security and non-security improvements.
Microsoft also published Windows 10 KB4494441 for October
2018 Update as part of the Patch Tuesday, but users are
reporting a weird issue where the update would install two
For unknown reasons, Windows 10 KB4494441 has been
installed twice on a number of devices. Fortunately, Microsoft
has already acknowledged the bug and the company is expected to
share more details soon.
As per a Reddit
discussion, KB4494441 installs without any problems
when the user checks for updates via Windows Update. After the
system reboot, KB4494441 is re-offered to some users again and
it would require another reboot to finish the installation.
Windows 10 cumulative update isn’t offered for the third time
and it’ll display ‘You’re up to date’ message if you check for
updates again. Users have also noticed that the update will be
listed twice on the Windows Update history page.
“2019-05 Cumulative Update for Windows 10 Version 1809 for
x64-based Systems (KB4494441) (2) Successfully installed on
5/14/2019,” the history page reads.
“Yeah, I seem to be installing it for the second time as well,”
a user confirmed the problem in a Reddit thread.
It’s worth mentioning that you’ll not face any problems if the
update installs twice.
As mentioned, Microsoft has already acknowledged the problem
and it’ll share more details soon.
“Windows 10, version 1809 Update Tuesday update may install
twice. We are presently investigating and will provide an
update when available,” Microsoft acknowledged the bug in an
updated blog post.
