Taking no chances, I figured out that the INF file was OEM68.INF, so I moved that file and the OEM68.PNF files to another folder. I couldn't tell from my Internet searches if a rollback DELETED the previous driver or just made the substitution and left the previous driver files in place. As I mentioned in my original query, I did change the driver using Device Manager back to the MS default, but each new Windows Insider build installation would re-install the AMD_SATA drivers. Is there a later version of this SATA driver for the AMD SATA controller that I could try installing? I've attached a screen print of my Device Manager entry from the AMD SATA controller, showing it using the AMD driver v1.3.001.0276 which has passed Microsoft's hardware compatibility tests.

That will return my PC to good operation, but the next time an update occurs, the SATA driver gets reset to the AMD_SATA driver and I'm in trouble again. I checked on some of the Windows support forums, and the only solution I found was to replace the AMD_SATA driver with the generic one that comes from Microsoft. This is especially frustrating when trying to do an update, which usually requires a reboot. The effect of these continuous resets is that my disk activity light stays on continuously and it will take FOREVER to get my computer to shutdown or restart. This will last for long periods, but will eventually end, only to happen again after an indeterminant time. When I utilize the only AMD_SATA driver on my desktop with Windows 10 (on the Insider Program), my computer goes into periods where there will be continuous resets on the SATA port.
