Driver sd need updating
It appears that Microsoft is blocking the May 2019 update as otherwise it can reassign the drive letters mounting the USB drive or SD card.
Interestingly, Microsoft has also confirmed that "The drive reassignment is not limited to removable drives.
Which surely begs the question of whether the May 2019 Windows 10 update should be released at all until this issue is resolved.
The pessimist in me, and unfortunately this tends to come to the fore whenever someone mentions Windows 10 updates given recent freezing problems, worries that this could turn into yet another "Microsoft borked my computer" moment should the update decide to reassign my hard drive.
Which is why this particular issue resonates so much.
Microsoft is admitting that there's a problem and will block installations of the update in order to prevent it. Or at least it would be were it not for that almost throwaway admission that internal hard drives can also be impacted by the update.
Internal hard drives can also be affected." The workaround suggested by Microsoft is to remove external media, be that a USB device or SD card, and restart the update installation process.
For Windows Insiders, this issue is resolved in build 18877 and later builds." Which, frankly, isn't good enough in my books.
Removing that and trying again isn't going to work, and neither am I if a drive reassignment happens and application software loading gets screwed for example.
I'm a security guy and am used to warning users about threats that could compromise their data, including Windows 10 vulnerabilities.
Drivers are typically installed and updated automatically whenever you connect the hardware to your computer, but you may occasionally need to use your computer's update tool to take care of a stuck driver.
If you're on a Windows computer, you can also view and update drivers from within the Device Manager program, and both Windows and Mac users can download and install drivers directly from a manufacturer's website.
