Windows Vista Customer Preview Program (CPP) allows registered users to download Windows Vista Beta 2, Release Candidate 1 (RC1) and Release Candidate 2 (RC2) together with valid product key or serial number to install, activate and use Windows Vista pre-RTM build for up to June 1, 2007. However, if you go to the program’s web page, and try to register and receive a product key, you will notice that Customer Preview Program is now closed and no new registrations are being accepted. However, you can still receive a valid and legitimate CPP (or RC1) product key with the following trick.

  1. You will need a Windows Live account (also known as MSN Hotmail, MSN Messenger, or Microsoft Passport account) user ID and password from here.
  2. Select your country in the form below, and click on Go.

    If the form is not working properly, go to this link.

  3. Login with your new Windows Live account that never been used to get Windows Vista product key or serial CD number (if it’s new one then it’s ok). Else you will have the following error message:

    Windows Vista RC1
