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

Anonymous

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.

This worked for me and I didn't need to use the media creation tool.

But what if the installation of this tool can't be completed because it's being interrupted by the failing message we are talking about?

Hello,

I had the same update problem as ToddAllen1:

I received the error message about the storage driver, but upgrading the driver did not help.

Then I tried the Media Creation Tool as recommended. First it downloaded windows, then, after 2 hours, the automatic search for Windows Update created the same error message about the storage driver as before.

I have no anti-virus except Defender.

Any suggestion?

After the intel upgrade, the iastorA.sys remains on the 15.2.0.1020 version! A new iasorAC.sys is present and has the new version 17.501.1021!

Renaming the iastorA.sys solved the problem. Windows version 1903 is installed now. Thx
