Windows 10 May 2019 Update is due in next month and hence Microsoft is now laying the groundwork for a smooth rollout of the update. The company has recently updated its support document in which they clearly mentioned that users who are using external USB storage devices or SD cards will have a hard time installing the May 2019 Update.
The main reason behind the blocking of May 2019 Update, according to Microsoft, is the occurrence of “inappropriate drive reassignment” on computers that have a USB drive or SD card attached to them.
“Inappropriate drive reassignment can occur on eligible computers that have an external USB device or SD memory card attached during the installation of the May 2019 update,” Microsoft explained. “For this reason, these computers are currently blocked from receiving the May 2019 Update.”
PCs that have USB device or SD card attached to them will see the below message.
If you are one of them who doesn’t want to remove SD card or USB drives for whatever reasons yet want to update your PC to the May 2019 update then this is not going to be the end of the road for you. Fortunately, Microsoft will be working on a fix to the “inappropriate drive reassignment” issue which will eventually be rolled out in future Windows 10 cumulative update. You’ll have to wait until Microsoft fixes the issue.
Assuming you won’t mind removing the USB drive or SD card if you have any, it is expected that you won’t run into any difficulties while installing Windows 10 May 2019 Update.
