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.

    The fact that the installer is blocking only some of the USB devices seems just another mistake of MS, they tried to prevent the problem that caused the dive letter reassignmentduring installation and for that they should have blocked any USB storage device. 

    Why do you accept the highlighted text as fact?

    I believe Microsoft is trying to find a way to install on systems which don't have the space needed on the OS partition to complete the install. 

    For years, the EFI system partition was being assigned a drive letter, in error, on some systems.  It has never happened to me, but has happened to many folks.

    The 32 GB partition size may be relevant because many systems had a 32 GB prefetch drive or tablets were sold with 32 GB drives.  Using Rufus to set up a Install Media drive my be outside the box since it creates 2 partitions, not just the FAT 32 maximum size partition of 32 GBs.

    But i agree, it is too bad the conversation seems to revolve around the install as opposed to the actual  build upgrade... I think I am going to make good use of the Sandbox in 1903..

    Saltgrass, 

    Why should all this make a difference on what type of USB stick is blocked out by the installer?

    In your case you said it worked fine with a 32GB Sandisk Glide, while in my case it fails with a 32GB Sandisk Ultra on 5 different machines.

    I use the same 32GB SanDisk Ultra and I have no problem doing any upgrade using any version of windows from 1709, 1803, 1809 or 20H1.

    It only fails with the released version 1903. They just need to fix it.

    I have never implied it mattered what model of USB drive was used, just the size.  I also cannot comment on your experiences, just mine....

    Saltgrass, 

    Size doesn't matter, but the type does I just tried with a 16GB Zheino USB device and the upgrade works fine. The installer is not blocking this one.
