Microsoft is blocking the May 2019 Windows 10 update from some computers with USB drives connected, but it gets worse…
Microsoft has confirmed that certain Windows 10 based computers will not be able to upgrade to the May 2019 update if they have either an external USB device or SD memory card attached. Interestingly, Microsoft has also confirmed that “The drive reassignment is not limited to removable drives. Internal hard drives can also be affected.” And that. for me, is where the real problems begin.
