You might have read our article about the Windows 7 Tech Guarantee Programback in November which basically stated that Windows Vista users might receive a free Windows 7 upgrade depending on the time of their purchase. Some new information came to light that have not been confirmed yet by Microsoft.
Techarp, a technology website, has listed the requirements for receiving a free Windows 7 upgrade. They do mention that the program is optional meaning that not all OEMs might participate.
A new PC has to be purchased between July 1, 2009 and a date that has not been announced yet. A pre-installed version of either Windows Vista Home Premium, Windows Vista Business or Windows Vista Ultimate has to be supplied with the PC that must have a valid Certificate of Authenticity (COA) attached.
The upgrade paths are straightforward:
1. Windows Vista® Home Premium -> Windows® 7 Home Premium
2. Windows Vista® Business -> Windows® 7 Professional
3. Windows Vista® Ultimate -> Windows® 7 Ultimate
