With Windows 10’s big May 2019 Update coming very soon, Microsoft is warning everyone about a very weird bug that could block the update from installing.
Reportedly, the update is blocked on PCs that use a USB hard disk, like a thumb drive or machines with an SD Card in the SD Card reader.
“Inappropriate drive reassignment can occur on eligible computers that have an external USB device or an SD memory card attached during the installation of the May 2019 update,” said a Microsoft support article.
Drive letter change
So, if you had a USB drive with the D: letter assigned to Windows, the May 2019 Update could change it to E:. While that might not be a huge problem for consumers, it could be a big headache for business machines. The drive letter change could be a big problem for them.
The issue will be resolved
Microsoft says “this issue will be resolved in a future servicing update for Windows 10.” However it won’t be available at the launch of the May 2019 Update. So this is an advance warning to users so they can be aware of the bug until Microsoft fixes the issue. Though, it is a little weird that it’s taken Microsoft so long to detect this bug. The update is due next month and Microsoft is just now noticing it. The company has millions of Windows 10 testers helping flagging bugs. Why would it take this long for them to find this USB storage issue?
Regardless though, it does seem Microsoft is being a little more careful than it was with the October 2018 Update. That update resulted in some file deletion issues. Microsoft doesn’t want that happening again this time around.
