The microcode update is always lost between reboots. This is e.g. why the Linux kernel can update the microcode during early boot.

The only way to make microcode updates stick between reboots is with a BIOS/EFI firmware update (some vendors provide firmware updates with microcode updates.). Then the microcode update gets applied during every boot automatically.
