KB4090007: Intel microcode updates RRS feed

All replies

  • Hello,

    Based my understanding, you should install the OS patch for the Windows system, meanwhile, you also need to install the patch for firmware from the PC manufacture.

    Best regards,

  • No, this is an alternative to a BIOS update.

    As long as your processor's microcode is updated one way or another you will be protected against Spectre variant 2.

    Note though that the Microsoft microcode updates don't (yet?) include microcode for every processor for which microcode has been released. You need to check your processor is included if you are going to rely on Windows to update your microcode.

    Also note that microcode updates don't stay in the processor for good. When it's powered down or rebooted the processor reverts to it's original microcode with the vulnerability present. Therefore if you dual boot with an OS which doesn't include the microcode update that other OS will be running without the new microcode.
