Windows 10 May 2019 Update (19H1/1903) Upgrade Blocks
« on: April 24, 2019, 03:54:35 PM »
Microsoft published support bulletin, Windows Update blocked because of drive reassignment yesterday.  The issue is as follows:
Quote
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. For this reason, these computers are currently blocked from receiving the May 2019 Update. This generates the error message that is mentioned in the "Symptoms" section if the upgrade is tried again on an affected computer.
Although the issue will be resolved in a future servicing update for Windows 10, the simple workaround is to remove the external media and restart the May 2019 Update installation.

When I saw that yesterday and it said to remove all USB devices, I had to dig deeper. Most computers today have USB keyboards and mice and if you had to remove them, that wouldn't work.

Then I discovered it is USB storage devices. Phew.

UPDATE 4/29: Current List of Upgrade Blocks for the May 2019 Update (19H1):

    If you have an external USB device or SD memory card is attached to your PC, you will be blocked from updating to the May 2019 Update. See this support article for details. If you remove any external USB devices and/or SD memory cards, the update should proceed normally. This issue will be resolved in a future servicing update for Windows 10. For Windows Insiders, this issue is resolved in Build 18877 and later builds.
    If you have older versions of anti-cheat software used with games installed on your PC, you will be blocked from updating to the May 2019 Update. Some older versions of anti-cheat software may cause PCs to experience crashes after updating to the May 2019 Update. This block is specific to older versions of anti-cheat software. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of hitting this block, please make sure you are running the latest version of your games before attempting to update the operating system.
    If you have redirected any Known Folders (for example: Desktop, Documents, Pictures), an empty folder with that same name is created in your %userprofile% directory when you update. Your Known Folders are redirected if you chose to back up your content to OneDrive using the OneDrive wizard, or if you chose to keep your content backed up during the Windows Out-of-box-Experience (OOBE). You may have also redirected your Known Folders manually through the Properties Dialog in File Explorer. This issue does not cause any user files to be deleted and a fix is in progress
