I have an XPS 9350, and when I attempt to update to the 1903 windows update I get the following 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.

/

I clicked on the link for more information, and saw that I needed to update the driver to the recommended version, 15.9.6.1044. This was unsuccessful, and so I tried the latest version directly from Intel. I rebooted through all of these attempts.

The same error message occurs despite the version of the driver that I have.
