Windows 10 update fails with error about iastora.sys after upgrading to recommended Intel Rapid Storage version

I'm attempting to update Windows 10 to 1903. The update failed with the error message "The inbox storage driver iastora.sys doesn't work on these systems and causes stability problems on Windows. Check with your software/driver provider for an updated version that runs on this version of Windows." This error led to a support page at https://support.microsoft.com/en-us/help/4514156/updating-to-windows-10-version-1903-on-devices-with-certain-versions-o recommending that the driver be upgraded to version 15.9.6.1044.

I have upgraded the driver accordingly (see attached screenshot), and rebooted the machine afterwards, but still receive the same error. I have also tried uninstalling and reinstalling the driver, and attempting the upgrade with the driver uninstalled, but receive the same error message no matter what version of this driver is installed, or indeed if it is installed at all.

Hi Todd. I'm Greg, an installation specialist and 10 year Windows MVP here to help you.

That's the buggy Windows Upgrade Advisor which is often wrong and wastes a lot of time. For this reason it's much more stable to Upgrade using the media itself and not buggy Windows Updates or Upgrade Advisor.

Install the Media Creation Tool from this link http://windows.microsoft.com/en-us/windows-10/m..., choosing Download Tool Now, install the tool, open it and choose Upgrade this PC Now. . This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.

If any problems report back the verbatim error and number, then continue with these steps for overcoming Version Upgrade problems: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.

    Your solution does not work!  If you can read, people have already installed the new Intel thingy and we are still getting the error message whether we click on your link to install the update or do it automatically.  Try again, please to fix this problem most likely affecting millions of people!!!  Nothing worse than a tech guy who sounds confident in his solution but fails miserably in the actual result.

    Thanks for your insight.  I began with DISM, repaired the store and seems like something else, couldn't complete windows repair - at around 85% failure would occur due to missing parts of a kb update package.  I downloaded and extracted the kb to a folder as a cab, but even when I finally figured out how to use package manager through powershell these 168 or so kb files missing weren't there.  The best that I can guess these are third party generated files, but I could be wrong.  In any case, I decided to upgrade to the May Windows 10 version in hopes of clearing this issue.

         Of course it was then that I got the Intel RST needs to be updated, updated it and still windows wouldn't update.  Finally hunt down the driver responsible to see that intel didn't clear the old, unused driver which windows update detected and assumed was the current driver.  I renamed that file and applied your solution, likely either would have solved the issue alone, and finally have the May update installed.  Now back to DISM to see if windows is working properly lmao.

         Thanks!  (and good luck to us all!)

    What if there seems to be no iastora.sys file anywhere on the computer?
