How to remove Windows 2008 R2 registration keys?

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!  :)

When you install the windows server 2008 that time install window server without cd key.

When ask the cd key that time skip and continue your installation.

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!
