Windows Server 2012 KMS Service Activation

Now we have the Windows Server 2012 and Windows 8 RTM bit form our Volume License we need to get some housekeeping done. The first thing we do is setup or update our KMS Service.

In our case it is running on Windows Server 2008 R2 so we need to do a couple of things.

Install the following update: An update is available for Windows 7 and Windows Server 2008 R2 KMS hosts to support Windows 8 and Windows Server 2012 as described in KB2691586. This is also the place where you can request this hotfix.  If you don’t install this hotfix registering a Windows Server 2012  KMS will throw an Error: 0xC004F050 The Software Licensing Service reported that the product key is invalid

So request the hotfix and install it from an elevated command prompt. Just follow the instructions and you’ll be fine Smile


Once you’ve clicked OK the installation will start


After that’s finished you will be asked to restart the server. Do so. Just restarting the KMS service ("net stop sppsvc" and "net start sppsvc") doesn’t suffice.


Now we have that out the way we can start putting our brand new KMS key into action.

Let’s take a look at what is already running:

slmgr.vbs /dlv => clearly the Windows 2008 R KMS key

Uninstall the current KMS key using slmgr.vbs /upk, please use an elevated command prompt Winking smile



Now you can install the new KMS key. The key listed here is obviously a demo one Winking smile If you run in to any issues here, restarting the KMS Service can help. Try that first.




Now activate your brandnew KMS key running slmgr.vbs /ato



Show what’s up and running now by running slmgr.vbs /dlv again and as you can see we’re in business to activate all our Windows Server 2012 and Windows 8 hosts. Life is good Smile


Windows Server 2012 Bits Available for Download for Volume Licensing Customers

A long awaited day has arrived. The bits of Windows Server 2012 RTM are available to us. Ever since the BUILD conference in September 2011 a lot of us have been diving into this version with enthusiasm and amazement for what’s in the product. As a matter of fact I’ve “sold” projects based on Windows Server 2012 internally since October 2011 because we were that impressed with what we saw.

  • Grab the bits on the Microsoft Volume Licensing site (from August 16th onwards). I whish I could tell you it’s also on TechNet or MSDN but no joy there so far.

So we’ve been pouring over the product and the information available, gradually gaining a better understanding of what it can do for us and our businesses. That meant building labs, testing scenarios, presenting on the subject at various occasions.  There was also a lot of thinking, dreaming and discussing ideas and options about what we can do this version of Windows. It has been very busy for the past 11 months but I’m also very happy to have had the opportunity to attend several summits and conferences where I met up with colleague, fellow MVPs, MSFT employees who all shared the enthusiasm for this release and what it means for Hyper-V and the Private/Hybrid Cloud.


So to all of them, ladies & gentlemen, my on line community buddies form all over this planet, it’s been a blast Smile. They have been very helpful in all this as have been al the Microsoft employees who’ve answered and discussed all the questions/ideas we threw at them. I would like to thank all of them for their time, their patience and the opportunities given to us. I can offer those guys & galls just one reward: the fact that from day one we are taking this in production and gradually will do so for all our infrastructure systems and so on. It’s a no brainer when you’ve worked with the RC and seen what Windows Server 2012 can do. And no, I’m not forgetting Windows 8. SMB 3.0 & Direct Access and Windows to go alone make that a sweet proposition, but I got those bits already.


Well, the downloads are running and the installation of our first production Hyper-V Cluster and infrastructure servers can start as soon as that’s finished (we’ll lead Brad, we’ll lead Winking smile). After some initial tests these will be taken into service and that last feedback will provide us with the go or no go for the rest of our infrastructure. The speed & completeness of our move depends partially on how fast System Center 2012 SP1 brings support for Windows Server 2012.

So future blog posts and my next presentations will spiced with some real life production experience with the RTM bits. May all your roll outs be smooth ones!
