I reinstalled this update and have rebooted twice now. It's not near as bad as before but I can still tell a difference. Inspectre says I am fully protected even though my CPU was not on the list.

Should I believe Inspectre and be happy it says I am fully protected?

This is what I have been waiting for. Toshiba have declared that they will not be issuing a bios update for my machine, so a microcode update from MS was my only hope. Finally.... *Party

BTW, this is a welcome change....

...previously these microcode updates were only available from the Microsoft Update Catalog.

Yes Bree, I know what you mean with regard to the Toshiba bios update. Thank you Bree for (indirectly) making me aware of the GRC InSpectre utility and thank you Shawn @Brink for the KB4100347 Intel microcode update.
