Update to Windows 10 1903 requires updated Intel Rapid Storage Technologies

Anonymous

After receiving the notification, I updated my Dell Inspiron 5000 series with an update from Dell.  This update installed successfully as indicated:

However, the file that is blocking the Windows update, iasota.sys, is the old version that was present before I updated RST (note that other iasot*.sys files are newer):

Any idea on what can be done to workaround the problem?

Is the iaStorA.sys file obsolete and no longer needed now that the RST driver has been updated?  If yes, should I simply rename the file to iaStorA.old and attempt to update Windows again?

Do newer versions of Intel RST still use the older iaStorA.sys file resulting in the Windows Setup not recognizing that a compatible version of RST has been installed?  If yes, then do I have to wait for Microsoft to modify the Setup program so that it assesses RST compatibility by looking at something other than the iaStorA.sys version (e.g., the iaStorAC.sys version, which is the file that serves as the driver for the I/O SATA AHCI Controller?

    Hi Maurice -

    What's the SATA controller setting in UEFI/BIOS Setup?

    This bulletin just came out yesterday about this: https://support.microsoft.com/en-us/help/451415... I guess those with IRST were gated until now.

    The windows notification says you do not need to do anything now.  So is the solution going to come through the windows update eventually?  I have read about the solutions such as renaming the files and downloading the drivers, but for people who are not so savvy it gets a bit confusing.  Should we wait for the updates to come through the windows update process?

    The bulletin mentioned in the copy of Greg's post in the blue section above says that Microsoft anticipates a solution will be available in mid-August.  I do not know when the solution will be ready.  If you do not feel confident about renaming the files and downloading the drivers, I would wait for Microsoft to resolve this issue.  The new features in version 1903 are not critical so there is no harm in waiting.

    I suggest that you try to install 1903 in September.  If you are successful, then Microsoft solved the issue.  If you get the same message, wait a few weeks and try again.

    I have tried the solution above but it still did not work on my system.

    I was only able to rename three of the four iaStor*.sys files. The Sysinfo

    report shows iastorac.sys was started and could not be renamed.

    I ran Device Manager and right clicked on properties of the SATA controller listed.

    It shows another driver is being used.

    I created an image gallery so anyone can take a look at the screen captures

    showing what I looked at.

    If any further information is needed please ask.

    Thank You

    The post says rename iastora.sys.  It is only referring to that one file..

    I wouldn't worry about not being able to rename iastorac.sys.

    The SATA driver that your system is using after uninstalling RST is different from the one that was being used after I uninstalled RST.  It is also a very old driver (dated 2006), which is probably why you are getting the message that it is not compatible with Windows 10.

    I suggest you see if there is a more recent driver for your SATA.  In Device Manager, right click on the SATA Controller, select "update driver" and let Windows search for a more up-to-date driver.  If a updated driver is found and installed, try again to install Build 1903.

    If the driver cannot be updated in this way, then go to https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html and install the version of RST that Intel determines is the correct one for your system.  After installing and restarting, then check your SATA driver; it should be different from the one you have now and, if your computer uses the same one as mine, it will be iastorac.sys.  As long as the driver is not iastora.sys, then you can rename the iastora.sys file and install the 1903 update as described in Ready_Rover's August 1 post earlier in this string (also see my reply to Ready_Rover immediately following his/her post).
