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

Hello fg2001,

Today I created 32 GB USB installer from official ISO (Win10_1903_V1_English_x64.ISO), build 18362.30 using Rufus.

Clean Install to empty HDD was OK, but when I restore old image of 17763 and try update it using that same 32 GB USB I get same error message as shown on you original posting.

P.S. After over one year of using SSD's I was "shocked" how slow those HDD's are.

Hi Pauli O,

Yes, there is no problem with clean install. The block of USB is only when upgrading an existing system.

I tried also with the 32GB USB and it made no difference.

Not sure what type of 32GB USB device Saltgrass tried, but it sure fails to upgrade with my 32GB Sandisk. 

SSDs make an amazing difference with speed. I have an old Dell XPS 8300 that was getting too slow with the original HDD, when I installed an SSD for the operating system that machine came back to life :) 

B.T.W.

I just tried an upgrade from a different USB storage device and this one went through without the error message. Perhaps the trap of the installer doesn't recognize all types of USB storage devices.

This one that is not blocked is: 

USB 3.0 SCSI Disk device. It is an mSATA 64GB device in a USB 3.0 enclosure.

The other ones I have that are blocked are:

SanDisk Cruzer USB Device              (16GB)

SanDisk Ultra USB 3.0 USB device    (32GB)

I had good luck with a 32 GB USB drive where 8 GB and 16 GB failed.  Even with that, one system would not install until I removed an SD card.

Saltgrass,

Could you please tell what is the type and brand of the 32GB USB drive that worked for you ?

Apparently the installer is blocking only certain types of USB devices as you can see in my previous response to Pauli O.

Absolutely, there should be a link at the Download Windows 10 site to...

https://docs.microsoft.com/en-us/windows/release-information/status-windows-10-1903

Windows 10, version 1903 and Windows Server, version 1903 - Known Issues

It is mentioned so many times there this way: "NoteWe recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.".

Then - when the problem is resolved - the site should say whether the installer (Setup.exe) was also fixed (if it were involved).

Mine is on a SanDisk Ultra USB 3.0 (16GB) - which looks like offspring of your two failures. I'll try later to see whether mine will fail. I've been clicking for days, & 1903 hasn't been offered by Windows Update yet. I'll be upgrading from 1809, OS build 17763.529. I did do an upgrade this way before - was it 1809? If so, that is also on a SanDisk Ultra USB 3.0 (16GB), & 1803 was on the very same one that holds 1903 now. If it doesn't work, I'll have to decide between an ISO or to resume my wait.

Edit:  It took 3.5 minutes...

It did downloads up front which I guess got ...145. It seemed to pass two quick ~"checking your computer". But there it is. I don't want to waste a 32 GB USB on it to see whether Saltgrass's cure will work. I'm thinking about an .iso - but then still I will want a Setup.exe that will work on my SanDisk Ultra USB 3.0 (16GB).

My 32 GB drive is a Sandisk Cruzer Glide.  If you use inexpensive USB drives, they can cause problems with any install, but I don't use those types so my 16 GB and 8 GB drives are of the same relative quality as the Sandisk drive and were SanDisk or Kingston USB 3.0 drives..

If I had a failure on the first attempt, which happened 5 times out of 6, I always started over when I used the 32 GB drive.  The only normal install I got was using the 32 GB drive with the first attempt.

An install will download an additional 2 GB of data but I can't think why that would be a problem.  You do have the option to install while offline which might stop that download from happening.

Just in case it matters, I set up my USB drives using Diskpart and then copy over the install files from a mounted .iso file.

Saltgrass, 

 I don't think it matters which way you create the USB installation media. To be bootable on UEFI it needs to be formatted as FAT32.

Then you can just copy the files and folders from the mounted ISO.

That always worked fine before 1903 regardless of what type of USB stick.

I think that the trap they added in the installer for the USB bug may not filter out all types of USB drives, the one that works for you (SanDisk Cruzer Glide 32GB) may not be blocked by the trap.

As I said earlier I also got a USB device that eludes the block and the upgrade works fine without any issue from that USB disk.

Anyway the alternative that worked fine on all my machines was by doing the upgrade directly from the mounted ISO residing on an internal drive.

It looks to me that till MS fixes the installer setup.exe and eliminates the trap you can still get the problem even with installation media that includes KB4497935 (Build 18362.145).
