Changing Product Key on Windows 2003 (and SBS2003): I needed to change the product key on a SBS machine that was virtualized from an IT consulting customer’s machine. I did not want to re-activate the SBS machine using the customer’s key since the machine was still active and did not want to interfere with the proper operation of the production machine. I needed to install our MSDN key since this is the proper usage for that type situation.
In order to do this, when the product ask you to activate, chose the option to telephone a customer service representative to activate Windows. Then when the Activate Windows by phone comes up, chose the “Change Product Key” at the bottom to enter the new product key. Then cancel out of this operation and activate the windows over the internet as usual. [more]
