It is the brand name for some advanced virtualisation instructions. If you don't use virtual machines you can deactivate it.

It's to help optimize Virtual Machines.

Only needed if you use virtual machines (including XP Mode in Windows 7). Otherwise you can safely ignore it.

I highly doubt you can enable it any ways, so just leave it off.

VT-d is for virtualization of devices. Very few virtualization software even use it. Xen and VMWare ESXi, I think can use it. Not aware of others.

XP Mode only requires VT-x which, nowadays, is available even on the lowliest Celeron. Heck, I think Microsoft already dropped the VT-x requirement for XP Mode.
