As a courtesy, I used my TechNet keys to create a virtual test server. &nbsp;It turns out that I may be giving my test server to my customer to use as a live server, but I want to remove my keys before shipping it to them. &nbsp;I/they have no keys yet to replace my keys (but that will be their worry).<br />
