Yeah, new Win7 activation toolkit. Just get yourself Windows 7 releases from GRP or WZT, choose one of the activation methods and you’re good to go. Read instructions first.

Features:
» Input any Ultimate or Professional key (comes with 4 preset keys, I will add more for other versions when they are released)
» Automatically finds an available drive letter (if required)

Installer and uninstaller built in as standard
» Checks your Windows 7 version and build before install
» Automatically finds your active boot partition (May work on Dell PC's)
» Should work on all languages (Tested on simplified Chinese)
» Should work with hidden partitions
» Works on Windows 7 Ultimate and Professional editions
» Support for bios modded users
» Can activate Windows Vista SP2
» Improves Windows 7 boot time on a Mac (Compared to other loaders)

Version 1.6.3
* Fixed a missing serial issue caused by the new bios type detection feature
* Fixed an issue which would cause the application to start hidden behind other windows
