Someone by the nickname of Dr. Chang has managed to permanently activate Windows without buying it! I'm not sure about this because I have not tried Windows Vista and the crack yet. However, Dr. Chang has included screenshots to proof that it's true that he managed to crack Windows Vista activation. Dr. Chang tried pushing the date to Year 2016 (ten years ahead) and restarting several times, then moved the date back to 2006, the only thing that expired is his Antivirus. No more 180 days expiration problem and able to successfully receive Windows Updates for Windows Vista.
