Source: http://theinquirer.net/default.aspx?article=36022SOFTWARE AND hardware and networking and console firm Microsoft seems to have issued the wrong release of Windows Vista Business & Enterprise Editions to its Volume Licence Customers.
From the original release earlier this month, there were problems that arose with the install DVD as well as the installed versions of Vista.
A note on the web site said: "Reinstall Required: If you downloaded Windows Vista Business 32 Bit in English before November 22, 2006, please download and reinstall the updated version. We apologize for any inconvenience.."
Interesting: TheInquirer says Business and Enterprise VLK editions are affected, MS only mentions Business. I haven't noticed any problems with my Enterprise DVD and installation (other than being unable to activate it) and wonder what these problems were/are.
