Intel RST preventing windows update May 2019

Pavilion X9Z56EA#UUW
Microsoft Windows 10 (64-bit)

When attempting to install the Windows 10 May 2019 update, I receive the message:


"Intel Rapid Storage Technology (Intel RST): 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."


The installer directs me to the Microsoft support:


I have attempted the suggested fix to install the latest Intel RST driver ( from Intel's homepage, but the problem persists. I have also tried to install the particular driver recommended by MS (, but still no luck. Is this a known issue, and if it is, is it a HP or Microsoft issue?


Edit/update: Having run the installer of Intel RST driver (, the list of installed apps provided by Settings  > Apps > Apps & features will tell me that this is indeed the installed version. However, inspection of the particular file iastora.sys itself reveals that this has not been updated. It would seem that something is preventing the installer from updating iastora.sys, and that this is not detected by Windows, only by the Windows Update installer.
