Suppose I have a personal key through DreamSpark, but I'm still waiting for a company key (site licence or something). Can I install Windows Server 2012 on our dev server now with my personal key so I can start web socket development immediately, and then deactivate the key and enter a new one in a week or so?

The server's only being used by me anyway for development, and I'm just wondering if I can temporarily use my personal key until I get a company key, so that I can still use my personal key later for my own server at home.

There used to be a vbs script for 2008 servers that did this; however, there looks like a new method (from Microsoft) here that covers windows 8 and 2012 server.

Run the following command at an elevated command prompt: Cscript.exe %windir%\system32\slmgr.vbs /ipk

Note You can also use the Volume Activation Management Tool (VAMT) 3.0 to change the product key remotely, or if you want to change the product key on multiple computers.

The instructions I used for 2008 are:

Open the command prompt and navigate to %windir%\System32 directory

slmgr.vbs -cpky (this clears the KMS entry you may have)
slmgr.vbs -upk (this removes any product key installed)
slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (where the x’s are the new product key you want to use)
slmgr.vbs -ato (this activates the server)

Type slmgr.vbs for further options….
