writes Microsoft's new Windows 10 May 2019 Update has problems with some AMD Ryzen and Ryzen Threadripper based systems. Microsoft has blocked the installation of the latest version of Windows on Zen-based systems that are configured in SATA or NVMe RAID mode because an AMD driver can cause problems:
"AMD Ryzen or AMD Ryzen Threadripper configured in SATA or NVMe RAID mode. A driver is installed that causes stability problems on Windows. This driver will be disabled. Check with your software/driver provider for an updated version that runs on this version of Windows," the error message states.
Microsoft explains in a related support document that certain versions of AMD's RAID drivers are not compatible with the May 2019 Update. AMD explains things further in a support document of its own, saying that build 1903 contains new Device Input/Output Control (IOCTL) requirements for certain categories of device drivers.
"If a user attempts a clean install of Windows 10 May 2019 Update using device drivers that do not meet the new requirements, the PC may fail to reach the Windows desktop environment. If a user attempts a Windows Update upgrade from Windows 10 October 2018 Update (version 1809) to Windows 10 May 2019 Update, the update will be blocked until updated RAID drivers are installed," AMD explains.
To prevent this issue, users need to install the latest version of
AMD's RAID drivers prior to the installation of Windows 10 May 2019 Update.
