Welcome to the Dell Community @Frank-A 

Microsoft has placed a compatibility hold on Windows 10 devices that prevents them from upgrading to Windows 10 1903 if they are using older Intel Rapid Storage Technology drivers.

This is because certain versions of the software could cause Windows 10 to crash or not operate properly in version 1903.

Intel® Rapid Storage Technology (Intel® RST) User Interface and Driver Version: 17.5.1.1021 (Latest) Date: 7/10/2019

NOTE: I have notice that other models are having the same problem.

We can only hope that Dell is aware of the problem and is working on it???

I tried the latest version, 17.5.1.1021, for my XPS 8900 desktop, but still see the same message.  Any suggestions?

Also, which file do I need to apply between SetupOptaneMemory.exe and SetupRST.exe?

Thank you.

 

I'm having the same problem with an Inspiron 15 7569. Dell's Support Assist check shows no new driver at 31 July 2019

Dell's support page in my account at their web site also does not show any relevant driver

The message I received from Microsoft was:

"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"

I tried looking at Device Manager in Computer Management on my laptop thinking I might be able to update the driver from there. However after looking at every category of driver I couldn't find anything that specifically mentioned  Intel Rapid Service Technology (RST)

I am reluctant to try installing a driver directly from Intel's web site as there are warning about lack of compatibility with some OEM systems

Dell need to address this issue very very urgently as the Windows Update is rolling out now, after an initial delay

I solved the same issue on my inspiron by installing the following driver:

I hope it will work for you as well.

@Mr_Eri 

Yes they could give it a try.

Even though their models are not listed as a "Compatible System"

I have seen drivers from other models work.

What could go wrong???

Same problem here. I tried the SetupRST.exe from https://downloadcenter.intel.com/download/28966/Intel-Rapid-Storage-Technology-Intel-RST-User-Interface-and-Driver?v=t. I also tried the https://www.dell.com/support/home/pr/en/prdhs1/drivers/driversdetails?driverid=6w1fp. None of them worked. I also tried the SetupOptaneMemory.exe but got a message saying that it wasn't compatible. Any suggestions?

@MOTPR 

Please start a new post.

Post to the "Type" of laptop you have.

And include the "Model Number" of the laptop you have.

This thread now has multiple "Types" and "Model Numbers" posted.

There will not be a one solution fits all answer.

Thank you,

Hi I updated the driver from the link. When I check the Intel RST information it shows the new driver (17.0.2.1076). In device manager, the SATA driver is shown as iaStorAC.sys. (File version is 17.0.2.1076). However, the windows update is still stopped by the iaStorA.sys error. Is it safe to assume that this is now redundant and that I can delete/rename iaStorA.sys to allow the update to proceed?

joosujin,

Go to driver’s directory C:\Windows\System32\drivers find iastora.sys and rename it iastora.old.

Then install Windows 10 1903 update.

Best regards,
