Software Licensing Management Tool. Windows Activation and Key Management Service (KMS)
Syntax slmgr [MachineName [Username Password]] [Option] Key machinename The machine to administer, by default the current local machine. username An administrator equivalent user account for the remote computer. password The password for the user account on the remote computer. /ato Activate Windows license and product key against Microsoft's server. /atp Confirmation_ID Activate Windows with user-provided Confirmation ID /ckms Clear the name of KMS server used to default and port to default. /cpky Clear product key from the registry (prevents disclosure attacks) /dli Display the current license information with activation status and partial product key. /dlv Verbose, similar to -dli but with more information. /dti Display Installation ID for offline activation /ipk Key Enter a new product key supplied as xxxxx-xxxxx-xxxxx-xxxxx-xxxxx /ilc License_file Install license /rilc Re-install system license files /rearm Reset the evaluation period/licensing status and activation state of the machine /skms activationservername:port Set the Volume Licensing KMS server and/or the port used for KMS activation (where supported by your Windows edition) /skhc Enable KMS host caching (default), this blocks the use of DNS priority and weight after the initial discovery of a working KMS host. If the system can no longer contact the working KMS host, discovery will be attempted again. /ckhc Disable KMS host caching. This setting instructs the client to use DNS auto-discovery each time it attempts KMS activation (recommended when using priority and weight) /sai interval Sets the interval in minutes for unactivated clients to attempt KMS connection. The activation interval must be between 15 minutes and 30 days, although the default (2 hours) is recommended. The KMS client initially picks up this interval from the registry but switches to the KMS setting after the first KMS response has been received. /sri interval Sets the renewal interval in minutes for activated clients to attempt KMS connection. The renewal interval must be between 15 minutes and 30 days. This option is set initially on both the KMS server and client sides. The default is 10080 minutes (7 days). /spri Set the KMS priority to normal (default). /cpri Set the KMS priority to low. Use this option to minimize contention from KMS in a co-hosted environment. Note that this could lead to KMS starvation, depending on what other applications or server roles are active. Use with care. /sprt port Sets the port on which the KMS host listens for client activation requests. The default TCP port is 1688. /sdns Enable DNS publishing by the KMS host (default). /cdns Disable DNS publishing by the KMS host. /upk Uninstall current installed product key and return license status back to trial state. /xpr Show the expiry date of current license (if not permanently activated) Token-based activation: /lil List the installed token-based activation issuance licenses. /ril ILID ILvID Remove an installed token-based activation issuance license. /stao Set the Token-based Activation Only flag, disabling automatic KMS activation. /ctao Clear the Token-based Activation Only flag (default), enabling automatic KMS activation. /ltc List valid token-based activation certificates that can activate installed software. /fta Certificate Thumbprint [PIN] Force token-based activation using the identified certificate. The optional personal identification number (PIN) is provided to unlock the private key without a PIN prompt when using certificates that are protected by hardware (for example, smart cards).
All actions (other than displaying status) require elevated administrator privileges.
Slmgr.vbs script is not intended to work across platforms i.e. between Vista and Windows 7

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
Request the hotfix and install it from an elevated command prompt.
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
Now you can install the new KMS key.
slmgr.vbs /ipk xxxx-xxxxx-xxxxx-xxxxxx-xxxxx
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 R2 and Windows 8.1 hosts.
Notes:
SLMGR /UPK may be necessary in some organisations. Without this the new key wouldn’t activate.
The KMS key activates:
•Windows Server 2008 R2
•Windows Server 2008
•Windows 8
•Windows Server 2012
•Windows 7
•Windows Vista
There is no requirement to have any W2K12/Windows 8. So it doesn’t matter, you can do that update, never even install a new KMS activation key and even if you do never activate any Windows Server 2012 / Windows 8. Even if that counter is reset doens’t matter either. The moment you reach the required number it just starts counting again.There is nothing dangerous or magic about that counter bar from people’s tendency to sit around watching it count. KMS if done well is set en forget until a new OS arrives and that you just update the KMS host. Nothing to worry about and if you have Volume Licensing so Microsoft support will help you when in doubt. KMS is loose that you could blow it up and take weeks to set up a new one, meanwhile
the company will keep running. All of this very well documented http://technet.microsoft.com/en-us/library/ff793418.aspx and here’s the entry point for all Volume activation info http://technet.microsoft.com/en-us/library/ff719787.aspx
Server VL VOLUME_KMS_2012_C_channel activates:
Windows Vista Business
Windows Vista Enterprise
Windows 7 Professional
Windows 7 Enterprise
Windows 8 Professional
Windows 8 Enterprise
Windows 2008 (all editions)
Windows 2008 R2 (all editions)
Windows Server 2012 (all editions)
Activation on the Enterprise client machines- Open cmd prompt and enter: slmgr.vbs /ato
