Since Windows Vista, Windows incorporates enhanced anti-piracy feature in the form of that incorporates Windows Product Activation (WPA) and for retail users. In addition, corporate customers with volume licensing agreement now also have to activate each of the computers in their network under Volume Activation with either Multiple Activation Keys (MAK) or on-premise volume license key-management service (KMS) host or server for networked environments with 25 or more machines. Besides, OEM computer products preinstalled in factory is protected with System Locked Preinstallation (SLP 2.0) where BIOS is included with signed Windows Marker and SLIC table for instant activation. All these activation processes make use of Software Licensing Manager (SLMgr) module, also known as Windows Software Licensing Management Tool in Windows, a VBScript called slmgr.vbs that keeps track of licensing details. SLMgr script allows users to query the current installation and see details about Windows installation and its activation and licensing status. SLMgr.vbs can also be used to input or change 25-character product key that determines which Windows OS edition allowed to install and activate, and which also tells the Setup program whether you’ve purchased a full or upgrade license. To activate online or against KMS server, users or Windows GUI need to make use of the SLMgr module too. Most of the licensing operation in Windows can be done via graphical user interface. If you’re power user, you can access to all options, flags and settings of the SLMgr.vbs command script. To run the script, logon with an user account with administrator rights, and open an. The syntax and options that are available for slmgr.vbs command: Syntax of SLMgr slmgr [machinename [username password]] [option] machinename is local or remote computer or PC that wants to administer. By default, if no machine name, user name and password is specified, current local machine is assumed. ![]() ![]() Username is administrator equivalent user account to login into the computer. Password is password for the user account. I am so confused. All I know is that I got this laptop (HP G70) as an 18th birthday present from my dad who bought it in New Jersey I believe and it is a genuine Windows Vista Home Premium. I just started having trouble with it maybe a couple months ago saying an unauthorized change was made to the system with error: 0x0C004D401 and I have no idea what to do because now I just got a notification that I have 30 days to fix the 'not genuine' issue and the validation check process at: won't ever finish. I really need help and I want to access my computer like normal! I DO have a genuine Windows Vista bought from a U.S. Please help me! Applies to • Windows 10 • Windows 8.1 • Windows 8 • Windows 7 • Windows Server 2012 R2 • Windows Server 2012 • Windows Server 2008 R2 Looking for retail activation? • There are three possible scenarios for volume activation of Windows 10 or Windows Server 2012 R2 by using a Key Management Service (KMS) host: • Host KMS on a computer running Windows 10 • Host KMS on a computer running Windows Server 2012 R2 • Host KMS on a computer running an earlier version of Windows Check out. Key Management Service in Windows 10 Installing a KMS host key on a computer running Windows 10 allows you to activate other computers running Windows 10 against this KMS host and earlier versions of the client operating system, such as Windows 8.1 or Windows 7. Clients locate the KMS server by using resource records in DNS, so some configuration of DNS may be required. This scenario can be beneficial if your organization uses volume activation for clients and MAK-based activation for a smaller number of servers. To enable KMS functionality, a KMS key is installed on a KMS host; then, the host is activated over the Internet or by phone using Microsoft’s activation services. Configure KMS in Windows 10 • Open an elevated command prompt. • Enter one of the following commands. • To install a KMS key, type slmgr.vbs /ipk. • To activate online, type slmgr.vbs /ato. • To activate by using the telephone, type slui.exe 4. • After activating the KMS key, restart the Software Protection Service. For more information, see the information for Windows 7 in. ![]() Configuring KMS Clients. Volume License editions of Windows Vista. The Slmgr.vbs script reports activation success or failure and provides a result code.

Key Management Service in Windows Server 2012 R2 Installing a KMS host key on a computer running Windows Server allows you to activate computers running Windows Server 2012 R2, Windows Sever 2008 R2, Windows Server 2008, Windows 10, Windows 8.1, Windows 7, and Windows Vista. Note You cannot install a client KMS key into the KMS in Windows Server. This scenario is commonly used in larger organizations that do not find the overhead of using a server a burden. Note If you receive error 0xC004F015 when trying to activate Windows 10 Enterprise, see. Configure KMS in Windows Server 2012 R2 • Sign in to a computer running Windows Server 2012 R2 with an account that has local administrative credentials. • Launch Server Manager. • Add the Volume Activation Services role, as shown in Figure 4. Adding the Volume Activation Services role in Server Manager • When the role installation is complete, click the link to launch the Volume Activation Tools (Figure 5). Launching the Volume Activation Tools • Select the Key Management Service (KMS) option, and specify the computer that will act as the KMS host (Figure 6). This can be the same computer on which you installed the role or another computer. For example, it can be a client computer running Windows 10. Configuring the computer as a KMS host • Install your KMS host key by typing it in the text box, and then click Commit (Figure 7). Installing your KMS host key • If asked to confirm replacement of an existing key, click Yes. • After the product key is installed, you must activate it. Click Next (Figure 8). Activating the software The KMS key can be activated online or by phone. See Figure 9. Choosing to activate online Now that the KMS host is configured, it will begin to listen for activation requests. However, it will not activate clients successfully until the activation threshold is met. Verifying the configuration of Key Management Service You can verify KMS volume activation from the KMS host server or from the client computer. KMS volume activation requires a minimum threshold of 25 computers before activation requests will be processed. The verification process described here will increment the activation count each time a client computer contacts the KMS host, but unless the activation threshold is reached, the verification will take the form of an error message rather than a confirmation message. Note If you configured Active Directory-based activation before configuring KMS activation, you must use a client computer that will not first try to activate itself by using Active Directory-based activation. You could use a workgroup computer that is not joined to a domain or a computer running Windows 7 or Windows Server 2008 R2. To verify that KMS volume activation works, complete the following steps: • On the KMS host, open the event log and confirm that DNS publishing is successful. • On a client computer, open a Command Prompt window, type Slmgr.vbs /ato, and then press ENTER. The /ato command causes the operating system to attempt activation by using whichever key has been installed in the operating system. The response should show the license state and detailed Windows version information. • On a client computer or the KMS host, open an elevated Command Prompt window, type Slmgr /dlv, and then press ENTER. The /dlv command displays the detailed licensing information. The response should return an error that states that the KMS activation count is too low. This confirms that KMS is functioning correctly, even though the client has not been activated. For more information about the use and syntax of slmgr.vbs, see. Key Management Service in earlier versions of Windows If you have already established a KMS infrastructure in your organization for an earlier version of Windows, you may want to continue using that infrastructure to activate computers running Windows 10 or Windows Server 2012 R2. Your existing KMS host must be running Windows 7 or later. To upgrade your KMS host, complete the following steps: • Download and install the correct update for your current KMS host operating system. Restart the computer as directed. • Request a new KMS host key from the Volume Licensing Service Center. • Install the new KMS host key on your KMS host. • Activate the new KMS host key by running the slmrg.vbs script.
