How do we update BIOS in a Windows 11 S Mode system

[mypcsad]

Noticed a BIOS update in HP support. Windows 11 S mode will not allow BIOS update unless you switch out  of S mode. Don't want that. How can we load the update while still in S mode? Will HP ever put the update in the Windows update channel? (Then the computer can download and install)????

You have to get the device out of S mode, and turn off secure boot and any other security-specific devices in UEFI (don't forget the switch code needs to be typed in after reboot to actually turn off any security settings!). Then, go to MS Store and switch out of S mode (once you do this, you cannot go back to S mode). Restart, then go to HP and get the correct updates for your device and you will be solid. If anything goes bad, just go to MS and Windows 11 and grab the media creation tool and a copy of Windows 11 (do you have your license key? if it is Digitally Signed Windows already has it, so no worries) then reset your device. I suppose you could use the HP reset option, as long as you did not tinker with the hardware, add devices or memory, etc. But if you did, you will need to use the MS Windows tools, as the HP tools will fail.
