From my understanding, the microcode is the firmware of the CPU.
It's usually upgraded by a BIOS update or by Windows update. Windows update send driver/firmware updates, security patches or general updates if the vendor wants to support that way of distribution.
I think it's quite device specific and method specific whether the microcode can be upgraded and downgraded the same way.
- shawnz 6y agoThe other poster is correct... microcode can be upgraded by BIOS update or Windows update, but the update doesn't persist on the CPU itself after a reboot (it has to be reapplied every boot, by either BIOS or Windows)
