Microsoft blocks windows 10 may 2019 on those pcs with external drives

The last update of Windows 10 May 2019 Update gives us a very curious bug, in which if you have a Windows 10 computer with update 1803 or 1809 (April and October 2018), you will not be able to install the latest version unless remove all USB storage devices and connected SD cards.

Windows 10 May 2019 Update brings a curious bug

Officially this update will be available next month, but users who can and can access it have encountered this problem.

The bug is related to setting the external media drive letter (USB-SD) which can change during the update installation and create conflicts with other drive remaps or prevent the necessary software from loading correctly after a upgrade. Therefore, it is necessary to disconnect any external media, restart the May 2019 Update and now.

Microsoft's workaround is to lock PCs with such settings, so they won't be able to install update in any way, unless they disconnect all external storage devices.

Explaining drive reassignment for external drives through an example, Microsoft concludes with a note: “Drive reassignment is not limited to removable drives. Internal hard drives can also be affected. " This case seems more serious. Those with multiple hard drives might have the same drawback.

This bug is only happening on those computers that have versions 1803 or 1809 of Windows 10, users with older versions should not have this problem. We hope Microsoft fixes this error when the update is released next month.
