Introduction
Windows activation and licensing are critical components in maintaining the legality and functionality of Windows systems in the IT environment. Ensuring that Windows is properly licensed and activated is not just a legal requirement but also a prerequisite for receiving important updates and support. In this context, PowerShell scripts emerge as powerful tools for IT professionals and Managed Service Providers (MSPs) to automate and streamline the process of checking Windows activation and license status.
Background
The provided PowerShell script is designed to detect the activation and license status of Windows operating systems. It is particularly valuable in environments where multiple machines need to be managed, ensuring that all are compliant with Microsoft’s licensing requirements. This script is a boon for IT professionals and MSPs, allowing them to quickly identify unlicensed or non-activated Windows installations, thereby avoiding potential legal issues and ensuring system integrity.
The script

Detailed breakdown
The script begins by defining a series of potential error codes and messages related to Windows activation. These are encapsulated within a PowerShell custom object, providing detailed information on the nature of the error, the type of activation (e.g., MAK, KMS), and troubleshooting steps.
In the process block, the script executes a series of commands:
- It retrieves the license status of Windows products using the Get-CimInstance cmdlet.
- The license status is then evaluated through a switch statement, translating it into an exit code that represents different states of activation and licensing.
- It runs slmgr.vbs -dli, a script that provides detailed information about Windows activation and licensing status.
- The script parses the output of slmgr.vbs to identify any specific activation errors and provides the corresponding troubleshooting information from the earlier defined custom objects.
Potential use cases
Imagine an MSP managing the IT infrastructure for a medium-sized business. They can schedule this script to run periodically across all Windows machines. If a machine is found with a non-activated or unlicensed Windows installation, the script can alert the MSP, enabling them to take corrective action promptly.
Comparisons
Traditional methods of checking Windows activation involve manual checks on each system or using disparate tools, which can be time-consuming and inconsistent. This script offers a centralized, automated approach, ensuring consistency and saving time.
FAQs
- How do I run this script?
- Run the script in PowerShell as an administrator.
- Will this script activate Windows for me?
- No, it only checks the activation status and provides troubleshooting steps.
- Can this script run on all Windows versions?
- It is designed for Windows 10 and Windows Server 2016 and above.
Implications
Incorrectly licensed or non-activated Windows systems can pose significant security risks, as they may not receive critical updates. This script helps maintain compliance and security standards within an IT infrastructure.
Recommendations
- Regularly schedule the script to run across all Windows machines in your network.
- Review and act on the script’s output promptly to maintain compliance.
- Ensure that PowerShell execution policies allow the running of scripts.
Final thoughts
In the realm of IT management, tools like NinjaOne can complement this PowerShell script by providing a comprehensive platform for monitoring, managing, and automating IT tasks. Integrating such scripts into a broader IT management solution like NinjaOne can enhance efficiency, ensure compliance, and maintain system integrity across an organization’s IT infrastructure.
