The driver as well.
If you want to avoid a fresh Win10 installation by using an image, where you had previously removed the in-box Intel RST(e) RAID driver v13.2.0.1022 and inserted the Intel RST RAID driver v11.2.0.1006 WHQL according >this< guide, I recommend to try this soft “downgrade”:
1. Uninstall the currently running Intel RST Software v13 series from within the Control Panel “Add/Remove Software” section and reboot.
2. Run the installer of the Intel Drivers & Software Set v11.7.4.1001 WHQL.
Although this will not be the best possible solution, you may get better results than now.
Good luck!
