The 1809 version of Windows 10, also known as the problematic update of October 2018, has received one more cumulative update, and with it, another bug for the list that this time is quite rare: the update is installed twice.

Initially reported on several Reddit threads, Microsoft has posted the problem on their known bugs page, indicating that they are currently investigating the bug and will provide more information when it becomes available.

Basically it is not yet known why this is happening, and seems to be a common problem, according to multiple users in the Microsoft and Reddit photos. Everyone reports that when you check for updates with Windows Update and proceed to install the update, after the corresponding reboot to install, the update starts installing again.

It is an important cumulative update that we recommend to install, and “at least” it does not cause you to hang up like the previous one.

While the strange bug is being investigated, the good news is that at least this doesn’t seem to cause any additional problems in the system, except for the space occupied by the double update, and we have to see the good side, if we take into account that the previous cumulative update slowed the system and even caused crashes.

As part of the usual Tuesday patches, Windows 10 received the KB4494441 update this week, one that in addition to bringing security updates, includes better and bug fixes, as well as enabling “Reptoline” by default, one of the important mitigation for Spectra that improves performance, so it is highly recommended that you install it.
