For anyone who is experiencing the 'Secure Boot Violation - Invalid Signature Detected', red box issue....(appeared after September MS Windows Updates and hosed encryption capabilities in Dv8P + some other laptops/tables)....
Today's MS Windows updates have fixed the secure boot issue!
So go into BIOS and enable Secure Boot, save config and exit, restart and...
Boom....no....red....'Secure Boot Violation'....box!
And.....(in my case) .... the encryption option has returned to the PC info page
Thank you Microsoft ....slow but much appreciated.

Just adding in for any future search refs, it was Microsoft's update KB3084905 which was re-issued to correct the issue with the Boot Manager (bootmgfw.efi).
