Atlast a complete crack for windows vista have been launched which works completely for me. I like to share it with you.

Until now, Microsoft has an upper hand, with no permanent or foolproof ways to crack or bypass Windows Vista activation request emerged. Instead, various workarounds and tricks to bypass, skip, delay, disable or spoof Vista activation has been suggestion, to various degree of success, such as extend evaluation period, rearm method, install Vista in future year, ‘frankenbuild’ Vista by replacing RTM build WPA files with RC build files,

activate against spoofed KMS server, or run and activate Vista with own local KMS server and etc. Now, there is new crack method that able to permanently stop the countdown timer of time left to activate Windows Vista, effectively running Vista OS in full functionality evaluation mode forever.

1. Install Windows Vista Ultimate edition (or other edition) without product key.

15. Optional: Press in Test button, and it will pop up a message says 4 timers are stopped. At this time, the counter should be freezed, Check with slmgr.vbs -dlv command, with the minutes left should be the same after a few minutes interval. If it’s the case, continue with the following steps to run the crack every startup.
16. In the Vista test crack window, click on “Install” button. You will be prompted with “Service installed” message if everything is done properly and correctly.
