Finally there is a small nifty utility that takes care of activating Windows Vista ( goodbye to crappy 30 days activation tricks :) )

1. Install Retail Windows Vista x86 WITHOUT product key.

2. Once Vista is installed extract the zip files.

3. Excute file “VistaActivator” and follow video instructions.
(If Windows ask you select “Allow”).

4. AFTER Reboot Windows will be activated.

Release name: Vista.All.x86.OneClick.Activator-CLoNY
Link : Vista Activation

Btw you need a torrent client to use the torrent file..

Head off to Slyck.com if you want details about torrent clients..
