Win 10 1903 May 29, 2019—KB4497935 (OS Build 18362.145) still fails the update from a USB stick.

According to the description of the fixes in KB4497935 the bug with the USB devices should have been fixed, but it still does not allow updates with installation media on a USB stick.

Fix description:

"Addresses an issue that may cause an external USB device or SD memory card to be reassigned to an incorrect drive during installation. For more information, see "This PC can't be upgraded to Windows 10" error on a computer that has a USB device or SD card attached"

I tried to do an update with installation media build 18362.145 on a system already at 18362.145 and still gets the error message below:

 

Is there a fix yet for this bug in the v 1903 release ? Which build do I need to get this bug fixed ?

I know that I can work around the issue installing from a local drive.

Also if I try upgrading from1903 to a preview 20H1 build 18908.1000 using a USB stick the update completes without this message.

I hope we don't need to wait for 20H1 to get this bug resolved.

    flash drive, 32GB. I used the media creation tool. Reinstall from 1809 to 1903

    PaulPChou, 

    Again, If you read the thread some flash drives have worked, so it would be useful if you can specify the brand and the model of yours.

    Samples of brands and models below, which one is yours, any of these or some other one ?

    Could your specify exactly what you used ?

    • Samsung MUF-128AB. Our top pick overall. ...
    • SanDisk Cruzer CZ36. Compact and secure. ...
    • Kingston Digital DataTraveler G4. ...
    • PNY Turbo. ...
    • SanDisk Extreme Pro. ...
    • Corsair Flash Survivor Stealth. ...
    • SanDisk Ultra USB-C. ...
    • Kingston Digital DataTraveler Elite G2.
    • Etcetera...

    hi,

    It is a usual USB drive, do not know how to call it. I reinstalled Win.

    What do you mean 'usual' ?

    Is it a flash drive or a regular HDD ?

    What is the brand, the model, and the size in GB ?

    Reinstall ? Do you mean , did you reinstall from scratch or di you update and existing system ?

    I can confirm that previews 19H1 and 20H1 work fine with the same USB devices that are failing with released 1903. I did several upgrades with the same USB sticks.

    They specifically added the block in 1903 to avoid the problem of drive letter reassignment, now that they fixed that problem they need to remove the block in 1903 installer.
