The latest update on Windows Update May 10, 2019 gives us a very curious bug in which if you have a team Windows 10 with the update 1803 or 1809 (April and October 2018) you will not be able to install the latest version unless you remove all USB storage devices and associated SD cards.
Windows 10 May 2019 Update brings a curious bug
Officially, this update will be available next month, but users who have access to it have encountered this problem.
The error is related to the configuration of the drive letter of the external environment (USB-SD) that may change during the installation of the update and create conflicts with other unit reassignments, or prevent proper downloading of the required software after the update. Thus, You need to exclude all external resources, restart the update May 2019 Update and now,
Microsoft's interim solution is to block computers with this configuration, so they can not install an update in any way unless all external storage devices are disconnected.
Explaining the redirection of units for external units by way of example, Microsoft concludes with a note: "Redirecting units is not limited to moving units. Internal hard drives can also be affected. "This case seems more serious. Those who have multiple hard drives can have the same problem.
This error occurs only on those computers that have versions 1803 or 1809 of Windows 10, users with older versions should not have this problem. We hope that Microsoft will fix this error when the update is published next month.
