FIX: Intel Rapid Storage Technology Driver Blocks V1903 Upgrade
FIX 1 – Upgrade Intel RST Driver
Intel Rapid Storage Technology driver provides enhanced performance and reliability on one or multiple serial ATA (SATA) or PCIe drives. Microsoft and Intel, both are aware of this issue. According to Microsoft, if Intel RST driver between version 220.127.116.112 to 18.104.22.1683 is installed on your system, this issue occurs. Users having Intel RST driver 22.214.171.1244 or later can upgrade to V1903 without any problem. So to resolve this issue, you need install/upgrade Intel RST driver to version 126.96.36.1994 or later.
FIX 2 – Uninstall Intel RST Driver
If you do not find upgraded version of Intel RST driver for your system model, try these steps (after creating System Restore point) to bypass the error:
1. Uninstall Intel RST driver from Settings app > Apps > Apps & features.
%sysroot%\System32\Drivers command and in Drivers folder, rename
3. Reboot to complete uninstall of driver and also to ensure your system boots up correctly.
4. If your system boots correctly, after restart, upgrade to V1903 and complete it.
5. Once the upgrade to V1903 completes, you can install Intel RST driver (version 188.8.131.524 or later), if you like. Or you can continue system using without Intel RST driver, if it works fine.
Hope this helps!
