How to remove Windows 2008 R2 registration keys?

Posted on 2012-09-16

As a courtesy, I used my TechNet keys to create a virtual test server.  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.  I/they have no keys yet to replace my keys (but that will be their worry).

I am looking for a method to simply remove my keys.  I am not interested in changing the keys.  Thanks in advance for thoughtful replies!  :)

    Per your link to the first article, open a command prompt as Admin and run:

    slmgr -cpky

    It returned a message box stating: "Product key from registry cleared successfully."

    Exactly what I wanted.  Thanks!
