Windows 10 May 2019 Update (version 1903) is now being blocked from installing on systems with certain versions of Intel Rapid Storage Technology (RST). Microsoft says May 2019 Update on some Intel PCs may cause stability problems and it could also break the inbox storage driver iastora.sys.
In a new
support document that is being blocked from indexing on search engines, Microsoft has documented a critical problem affecting devices with Intel Rapid Storage Driver version between 15.1.0.1002 and 15.5.2.1053. The issue appears to limit to specific Intel’s drivers and other devices with RST (but different driver version) does not seem to be having any problems.
If you have affected driver installed, Windows 10 version 1903 won’t show up on Windows Update page and upgrade block message would appear on Update Assistant Tool.
Microsoft says version 15.5.2.1054 or later is compatible with Windows 10 May 2019 Update, but users are recommended to install 15.9.6.1044 or newer.
“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,” Microsoft noted in a support document.
After fixing the outdated drivers, users have to restart their computer and check for updates again.
