As Windows 10 support ends, organizations must activate Extended Security Updates (ESUs) to keep devices secure. This guide covers ESU license activation, managing MAK keys, and integrating with Windows 365 for seamless security on physical and cloud PCs, ensuring compliance and protection.
Why Preparing Windows 10 Devices for ESUs Matters Now
Windows 10 support officially ended on October 14, 2025. Yet, many organizations still run critical systems on this platform. Without updates, these devices face growing security risks. That’s where Extended Security Updates (ESUs) come in. ESUs provide vital security patches beyond the end-of-support date. Preparing your commercial Windows 10 devices for ESUs ensures they remain protected against emerging threats. It’s a smart move to maintain business continuity and data security.“This represents a significant leap forward in keeping legacy systems secure,” said a Microsoft spokesperson.
How to Activate and Manage ESU Licenses Effectively
Activating ESU licenses involves several key steps. First, verify that devices run Windows 10 version 22H2 or later with the required updates installed. Next, locate your Multiple Activation Key (MAK) through the Microsoft 365 Admin Center. Ensure your account has the right administrative roles to access these keys. License activation can be done manually, via scripts, or through management tools like Microsoft Intune or Configuration Manager. Additionally, physical devices connecting to Windows 365 Cloud PCs must meet certain requirements, such as being Microsoft Entra joined and signing in regularly. Regular verification of ESU activation status is crucial. Use the command `slmgr.vbs /dlv` on devices to confirm licenses show as “Licensed.” This step helps IT teams maintain compliance and troubleshoot activation issues efficiently.Benefits of ESUs for Windows 10 and Windows 365 Users
ESUs extend your device’s security lifecycle without forcing immediate upgrades. For organizations leveraging Windows 365 Cloud PCs, ESU entitlements come at no extra cost under specific conditions. Devices must be Microsoft Entra joined or hybrid joined, and users need to sign in every 22 days. This integration reduces administrative overhead and enhances security posture. Furthermore, Windows 10 virtual machines in Azure environments automatically receive ESU coverage, simplifying management.“Extended Security Updates help enterprises stay secure while planning their next OS migration,” noted a senior IT analyst.In summary, preparing Windows 10 devices for ESUs offers a practical, secure bridge beyond official support. It empowers IT teams to protect critical assets and extend device lifespans seamlessly. Start your ESU journey today to stay ahead in the evolving cybersecurity landscape.
