• The Win10 1903 upgrade is now blocked on machines using older Intel Rapid Storage Technology drivers

    Posted on July 26, 2019 at 08:16 CDT by • Comment in the Forums

    UPDATE: Comments and new material have been moved here.

    It’s official Win10 version 1903 doesn’t like Intel Rapid Storage Technology (RST) drivers numbered between 15.1.0.1002 and 15.5.2.1053. If your machine has an older “Optane” driver — Fred Langa has a warning and analysis — you need to make sure that it’s updated to the latest version before trying to move to Win10 version 1903.

    Of course you aren’t going to jump into 1903 just yet, right? But it’s good that Microsoft is winnowing out these persistent problems. Kind of like, you know, a beta test should.

    From KB 4514156:

    If you are trying to update to the Windows 10 May 2019 Feature Update (Windows 10, version 1903), you may encounter an update compatibility hold and 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.”

    Intel and Microsoft have found incompatibility issues with certain versions of the Intel® Rapid Storage Technology (Intel® RST) drivers and the Windows 10 May 2019 Update.  If your device has an Intel® RST driver version between 15.1.0.1002 and 15.5.2.1053 installed, it cannot install the May 2019 Update.

    Versions 15.5.2.1054 or later are compatible, and a device that has these drivers installed can install the Windows 10 May 2019 Update. For affected devices, the recommended version is 15.9.6.1044.

    The latest version available on the Intel site is 17.5.1.1021, which dropped on 7/10/2019 . As you can see from the version numbers, Intel seems to update this driver frequently. As a consumer, you don’t want to update the driver directly. Instead, go to your hardware manufacturer’s site and get the latest RST driver set that they offer.
