No sooner than Microsoft announced the release to manufacturing of Windows Vista and Office 2007, pirates have announced that they have bypassed those products' copy protection schemes. The crack for Windows Vista (which is called "Vista BillGates") is not a true crack, as it replaces components from the final version of the operating system with those from earlier betas. This allows the would-be pirate to use a product key that worked with Beta 1, Beta 2, RC1, or RC2, with the Gold release of the operating system.
