Trouble continues for Microsoft’s May Update to Windows 10, with the software giant warning it does not like PCs connected to USB or SD Card storage devices.
A new advisory warns that “Inappropriate drive reassignment can occur on Windows 10-based computers that have an external USB device or SD memory card attached during the installation of the May 2019 update.”
What is “inappropriate drive reassignment?” Microsoft explains it as follows:
“Before the upgrade, the device would have been mounted in the system as drive G based on the existing drive configuration. However, after the upgrade, the device is reassigned a different drive letter. For example, the drive is reassigned as drive H.”
The problem affects internal drives as well as USB or other removable storage present in a PC when the May Update is installed.
Needless to say, Windows and applications that expect a file to be on one drive will not behave well when that file is elsewhere.
Which is why Microsoft has stopped the update, writing “these computers are currently blocked from receiving the May 2019 Update.” Users who try the update will instead see the message below.
The workaround for the problem is simple: remove USB or SD Card storage, then do the Update.
The workaround for Microsoft is less obvious: recent Windows 10 updates have caused data loss and broken security software, among other issues, leading the company to slow the release of the May Update and add features that give users more time before Updates become compulsory.
