Windows 10 May 2019 Update blocked on some Intel PCs

The series of Windows 10 May 2019 Update bugs is a neverending story. Microsoft recentl confirmed yet another problem with this update.

The Big M is taking all the precaution measures to save your Windows 10 machines from update havoc. The company has placed an upgrade block on Intel devices that rely on specific Intel Rapid Storage Technology (RST) versions.

According to Microsoft, this bug can trigger stability issues on some Intel machines. Not only this, but it may also affect iastora.sys –an inbox storage driver.

Microsoft explains in a support document:

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 (Windows 10, version 1903).

Upgrade block only for specific driver versions

Microsoft confirmed this critical issue affects all the RST driver versions starting from 15.1.0.1002 to 15.5.2.1053. This is a version-specific bug and all the systems running different driver versions should work fine.

Notably, you won’t see Windows 10 May 2019 Update in your Windows Update section if your system is running RST driver versions starting from 15.1.0.1002 to 15.5.2.1053.

Additionally, if you attempt to update your system via Update Assistant Tool, you will see an upgrade block message.

To safeguard your update experience, we have applied a compatibility hold on devices with Intel RST driver version between 15.1.0.1002 and 15.5.2.1053 installed from being offered Windows 10, version 1903 or Windows Server, version 1903 until the driver has been updated

A quick workaround

However, if you are running RST version 15.5.2.1054 or later, you can install Windows 10 v1903 on your system. Microsoft recommends that you install 15.9.6.1044 or newer to avoid all potential issues.

You need to contact your hardware manufacturer to check for the latest drivers. There might be a case that you can not find the compatible version at the moment.


Follow these steps to update outdated drivers in Windows 10 quickly and safely.


Alternatively, you should visit Intel’s website to download the latest version of Intel Rapid Storage Technology drivers.

To resolve this issue, you will need to update the Intel RST drivers for your device to version 15.5.2.1054 or a later. Check with your device manufacturer (OEM) to see if an updated driver is available and install it.

It is highly recommended that you reboot your machine to proceed with the upgrade process. Microsoft is working on fixing this issue.

We hope that a patch will be available very soon.
