If you are in a hurry to update to the May 2019 Update for Windows 10, better check you do not have any USB drives or SD cards plugged in, as they will still prevent you from installing the latest version of the OS.
At present this is one of the few known issues which would block your upgrade to the OS, with the issue as follows:
If you have an external USB device or SD memory card attached when installing Windows 10, version 1903, you may get an error message stating “This PC can’t be upgraded to Windows 10.” This is caused by inappropriate drive reassignment during installation.
To safeguard your update experience, we have applied a hold on devices with an external USB device or SD memory card attached from being offered Windows 10, version 1903 until this issue is resolved.
It is also, fortunately, one of the easiest to resolve – remove the removable drive, upgrade and Bob’s your uncle.
