Hyper-V - Enable and Disable in Windows 8

The page explains how to enable or disable the built-in Hyper-V feature in Windows 8 Pro or Windows 8 Enterprise. It says the user must be signed in as an administrator, and that Hyper-V client support requires a 64-bit version of those editions, a 64-bit CPU with SLAT, and at least 4 GB of RAM.
