Microsoft has allowed Windows Vista to be sold pre-activated (OEM version) from major OEM computer manufacturers such as Dell, HP, Lenovo, etc.
Team Paradox, a famous cracking group, has released a software based driver that emulates the BIOS of such an OEM computer and allows you to activate Windows Vista without connecting to Microsoft’s activation server. This utility does not Flash or change the BIOS but runs as a regular driver in the system.

Currently, it is only available for the 32-bit version.
