Posted on Wednesday April 24, 2019

Microsoft has published a support document today warning Windows 10 users that the impending May 2019 Update may not install on their systems if they use external USB storage devices or SD cards. From a report: The OS maker cited problems with "inappropriate drive reassignment" as the main reason for blocking the May 2019 Update. "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," the company said. "For this reason, these computers are currently blocked from receiving the May 2019 Update."
