One thing to note:
Acquires protection keys from RAM dumps
I would assume this means it would be able to access information from RAM, meaning that even if you have hibernation off, but say put the computer to "Sleep", RAM would still have power therefore any content is still stored on the RAM.
- Turn off hibernation
- Don't use sleep, instead do a full shutdown
- Lock HDD/SSD inside BIOS/EFI to prevent the system drive being swapped to another computer
- In Bios/EFI only have boot to hdd enabled, disabling things such as Network Boot (PXE/Network Image), USB Boot, and CD/DVD boot.
- Password lock your BIOS or RAID card(if you have one)
- Lastly use a password on your Windows account for login.
If you do this then you are pretty much safe in my opinion.
