How do I enable virtualization under 64-bit Windows 7 if the CPU is of a type that supports virtualization, but the program for changing UEFI settings does not offer any way to change whether virtualization is enabled or not?

Computer is an HP h8-1070t.
Version of Virtualbox desired is 4.2.16.
No more recent version of the UEFI is available.

If it is really not enabled in the CPU, then that is a question for HP (or the motherboard manufacturer) rather than here.

It is possibly more common, though, for it to be enabled at the CPU, but unavailable to VirtualBox because it is being used by something else. (Hyper-V seems the most usual suspect.)
