Update that enables Windows 7 and Windows Server 2008 R2 KMS hosts to activate Windows 10

Today, a blog reader notified me that Microsoft released an update that extends KMS for Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1 to enable the activation of Windows 10-based clients. Find it here.

I blogged about the update for Windows Server 2012 (R2) and Windows 8/8.1 before but now these older operating systems can also serve as KMS servers for Windows 10. All you need is the update that enables Windows 7 and Windows Server 2008 R2 KMS hosts to activate Windows 10 as discussed in KB3079821

Until now the workaround was to leverage Active Directory based activation for Windows 10 whilst you left your KMS server in place for the older clients. That works well and I have used it before. But with this update you can use your older KMS servers for all activations of windows clients.

Find and Update Your KMS Service Host Key To Activate Windows 10

I have done a series of blog post on preparing your KMS environment for Windows 10 activation. You should be set to go but the final step you need to take is update the KMS Service Host Key.  That means that in a corporate environment you’ll need to get your KMS Service updated so you can active the Windows 10 clients.

This one has tripped up some people when it comes to finding it. So we’ll address that here is as well.

Please note that only Windows Server 2012 (R2) or Windows 8, 8.1 or 10 can act as KMS Service Hosts.

Preparations

On the Volume License Servicing Center you cannot only get the bits but also the MAK and KMS keys. Normally you’d go directly to Downloads and Keys, filter down to what you’re looking for and find your KMS host key over there.That works for the Windows clients as before. But you cannot find and updated KMS Service key right now for Windows Server, that will probably work again when Windows Server 2016 goes RTM.

But for now you need to get the key by using a bit of a different path than you’re used to. Got to Licenses and select Relationship Summary

image

Navigate to the correct license id and click it to open the details of your license. There you select Product Keys

image

In the list of keys under that license you’ll find the KMS keey you need under product key for the product Windows Srv 2012R2 DataCtr/Std KMS for Windows 10

The Windows 10 KMS client keys are listed publicly by Microsoft. They are the keys of clients that activate against a KMS server. If you have you volume licensing media that’s normally the one in box with the client. You can read more in my blog Windows 10 KMS Client Setup Keys. If you don’t want or cannot use a KM you’ll need to use MAK keys on the clients. These are found on the Volume License Servicing Center as well when you have a valid license.

You also need to have installed an update on your KMS Service hosts. You can read all about that in my blog post KB3058168: Update that enables Windows 8.1 and Windows 8 KMS hosts to activate Windows 10  If you don’t install this update registering a Windows 10 KMS key will throw an error:

0xc004f015: The Software Licensing Service reported that the license is not installed.
SL_E_PRODUCT_SKU_NOT_INSTALLED

So grab the hotfix if it isn’t installed via Windows Update, WSUS etc. and install it from an elevated command prompt. Just follow the instructions and you’ll be fine Smile

Upgrading the KMS Service Host Key

It goes without saying that we’ll need to update the KMS Service Host key or we’ll see error 0xC004F015:

0xc004f042 – SL_E_VL_KEY_MANAGEMENT_SERVICE_ID_MISMATCH
he Software Licensing Service determined that the specified Key Management Service (KMS) cannot be used
.

This is also described in KB 3086418 Error 0xC004F015 while activating Windows 10 Enterprise using Windows Server 2012 R2 KMS Host

We take a look at our current situation by running slmgr.vbs /dlv which show us a Wk212R2 KMS Service host which can activate all servers & clients up to Windows 8.1/ Windows Server 2012 R2.

Uninstall the current  please use an elevated command prompt Winking smile

image

Now you can install the new Windows Srv 2012R2 DataCtr/Std KMS for Windows 10 key. If you run in to any issues here, restarting the KMS Service can help ((“net stop sppsvc” and “net start sppsvc“) . Try that first.

slmgr.vbs /ipk PIRAT-ESARE-NOTGE-TTING-AKEY!

Be patient, it’s not instantaneous.

Fall you wannabe pirates out there, that’s not a real key. As far as you are concerned this is the Navy Winking smile. If you’re, looking for illegal keys, cracks, keygens, activators or dodgy KMS virtual machines and such this is not the place!

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 R2 and Windows 10 machines as well as all lower versions down to Windows Server 2008 an Windows Vista.image

So we’re ready to roll out Windows 10 now via MDT and have our KMS server activate them.

Update Your KMS Service Key To Activate Windows Server 2012 R2 And Windows 8.1

It’s a great day as Windows Server 2012 R2 and Windows 8.1 bits have gone GA (“General Availability”). So it’s of to the Volume License Servicing Center to get the bits and the keys.

image

Before we start the roll out we need to either bring up a Windows Server 2012 R2 (or Windows 8.1) KMS host or upgrade the existing one that runs Windows Server 2012 or lower. In this example our KMS Service is running on Windows Server 2008 R2 so we need to do a couple of things.

Install the following update: KB 2885698: Update adds support for Windows 8.1 and Windows Server 2012 R2 clients to Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012 KMS hosts (see Windows Server 2012 R2 & Windows 8.1 KMS Service Activation).  If you don’t install this hotfix registering a Windows Server 2012 R2 KMS key will throw an error:

0xc004f015: The Software Licensing Service reported that the license is not installed.
SL_E_PRODUCT_SKU_NOT_INSTALLED

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

image

Once you’ve clicked “Yes” the installation will start

image

When the installation has finished you will be asked to restart the server. You need to do so. Just restarting the KMS service ("net stop sppsvc" and "net start sppsvc") doesn’t seem to suffice.

When your server comes back up you’ll be ready to install and activate the Windows Server 2012 R2 KMS key.

First we take a look at the current situation:

slmgr.vbs /dlv => clearly the Windows 2012 KMS key
image

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

image

Now you can install the new Windows 2012 R2 KMS key. If you run in to any issues here, restarting the KMS Service can help (("net stop sppsvc" and "net start sppsvc") . Try that first.

slmgr.vbs /ipk PIRAT-ESARE-NOTGE-TTING-AKEY!

Be patient, it’s not instantaneous.

The key listed here is for all you wannabe pirates out there, sorry, this is the navy. If you’re, looking for illegal keys, cracks, keygens, activators or dodgy KMS virtual machine for Windows  8.1 activation and such this is not the place Winking smile.

You now need to activate your brand new KMS key running slmgr.vbs /ato

image

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 R2 and Windows 8.1 hosts. I’m happy to report that our users will be enjoying Windows 8.1 on the clients in 2014 & the infrastructure in the data center will be benefiting form the goodness Windows Server 2012 R2 brings.
