Extending Windows 10 Support: A Guide to ESU (Extended Security Updates)

As Windows 10 reaches the end of its mainstream support, businesses and users who are not ready to upgrade to a newer version can opt for the Extended Security Updates (ESU) program. This ensures continued security updates and protection. Here’s a step-by-step guide to understanding and implementing ESU for Windows 10.

What is ESU?

Extended Security Updates (ESU) are a paid service that provides security updates for products beyond their official end-of-support date. This helps enterprises secure legacy systems while transitioning to newer technology.

Who Needs ESU?

Organizations that are unable to upgrade to the latest Windows version by the time support ends should consider ESU. It provides critical security updates, helping to protect against vulnerabilities.

How to Obtain ESU for Windows 10

Step 1: Verify Eligibility

Ensure your version of Windows 10 is eligible for ESU:

• Windows 10 Enterprise
• Windows 10 Education
• Windows 10 Pro

Step 2: Purchase ESU

1. Contact a Microsoft Partner: Microsoft partners or resellers can guide you through the purchasing process.
2. Microsoft Volume Licensing Service Center (VLSC): If you have a Volume Licensing agreement, you can purchase ESU through the VLSC.

Step 3: Deploy ESU License

After purchasing, you’ll need to activate the ESU license on each eligible device.

1. Access VLSC: Download MAK (Multiple Activation Key) from the VLSC.
2. Install and Activate Key:

   • Open Command Prompt as an administrator.
   • Enter the following command to install the ESU key:

     slmgr /ipk <ESU-MAK-Key>

   • Activate the key with:

     slmgr /ato <ESU-MAK-Key>

Step 4: Install Updates

Once the ESU license is activated, ensure that Windows Update is enabled to receive security updates.

1. Go to Settings > Update & Security > Windows Update.
2. Check for updates to download and install the latest ESU updates.

Step 5: Verify Installation

To confirm that ESU is activated correctly:

• Run the command slmgr /dlv in Command Prompt as administrator.
• Check for the “ESU Key” installation indicating successful activation.

Managing ESU

Monitoring

• Use Windows Update logs or third-party tools to monitor and verify update installations.

Renewal

• ESU is purchased annually, so remember to renew your subscription to ensure continuous updates.

Alternatives to ESU

If ESU does not fit your needs, consider:

• Upgrading to Windows 11: Offers new features and support.
• Cloud-Based Solutions: Utilize virtual desktop infrastructure for modern computing environments.

Conclusion

While ESU provides a temporary solution, planning an upgrade path to a supported operating system is crucial for long-term security and functionality. Use this guide to successfully implement ESU and protect your systems while you prepare for the future.
