Thank you for contacting the Intel® Communities.
I performed the update in our NUC5PGYB, BIOS 0950, 2GB of RAM and Windows 10* 64-bit.
I was able to use the hotkeys after the update.
Have you checked in the "support and options" section in the Intel® HD Graphics panel, if it has the hotkeys configured?
I look forward to your reply.
The hotkeys are configured also the hotkey ctrl+alt f8 isn't working, this one should always be enabled.
When I install the previous driver version 126.96.36.19900 i can use the hotkeys.
I have BIOS 0047 and windows 10 version 10.0.10586
Kind regards Simon
With the unit we have in our facilities, I was able to restore defaults with CTR+ALT+F8 hotkey.
Lets perform a BIOS recovery to the version 0047 to make sure everything is installed in your system.
Also, lets verify the hotkeys that are configured in your Intel® Graphics Panel.
I look forward to your outcome on this.
