How To Install The BIOS Spectre Update For Your PC [Guide]

The Intel Meltdown bug can be patched with an OS update. The same cannot be said for the Spectre bug. In order to fully protect your system, as much as is possible at the moment, against Spectre you need to update your BIOS. PC manufacturers have started releasing a special BIOS Spectre update. A BIOS update is not like an OS update. It isn’t going to install automatically. You have to download and install it yourself. Since BIOS updates very rarely roll out, and this is a critical update, we’re going to walk you through the whole process.

UPDATE: Intel has issued a warning users against installing its patches. It appears the patches have slowed down systems more than what Intel’s original estimates. If you’ve already upgraded, your manufacturer will issue a new patch for your BIOS, eventually. Everything is a mess at this point.

BIOS updates are installed the same way on all versions of Windows.

  • Close all apps and exit any and all UI modification apps such as Rainmeter
  • Make sure you’re connected to a power source. Do not rely on your laptop’s battery to carry you through the update. Make sure your power source will not fail you mid-update.

During The Update

The BIOS update will begin on your desktop inside the Windows UI however, your system will restart shortly and you will see your BIOS screen. Do not interfere with anything. Allow the update to install. The update will not ask you to confirm or select anything. Once the update is complete, your system will automatically boot to your desktop.

Booting After The Update

Ideally, you should be able to boot to your desktop without any trouble. That said, if you do experience any trouble booting to your system, shut it down or force shut it down and then turn it on. If you get stuck on the lock screen, don’t select the restart option from the power menu. Select the shut down option, and then turn it on once your system has fully shut down.

Are You Safe?

Run a tool called InSpectre. It will tell you if your system is protected against Spectre or not and what measures need to be taken to make sure that you are. If the BIOS update has patched the bug, you will see the screen below that says the system is now protected.
