Activating Windows 10 ESU Year 3

The ESU program for Windows 10 allows you to extend the receipt of critical security updates after the standard system support has ended. ESU Year 3 is the last year of extended support, which is why its activation requires meeting a valid condition: ESU Year 1 and ESU Year 2 must be previously activated on the device. The Year 3 key works as an add-on and does not replace the previous stages.

If the activation is not successful immediately, the most common cause is the lack of previous ESU licenses, incorrect system edition, or no connection to the Microsoft activation service. Below, you will find a simple step-by-step guide on how to properly activate Windows 10 ESU Year 3 using slmgr.

Step by Step

Before you start, make sure that:

  • you are using a compatible edition of Windows 10,
  • the system has all required updates installed,
  • ESU Year 1 and ESU Year 2 are already activated,
  • you have a valid ESU Year 3 Add-on key.

1. Open Command Prompt as Administrator

Click the Start menu, type cmd, and then select Run as administrator.

2. Install the ESU Year 3 Key

Enter the command:

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Replace XXXXX-XXXXX-XXXXX-XXXXX-XXXXX with your ESU Year 3 key.

After a moment, the system should display a message about the successful installation of the key.

3. Perform Online Activation

After installing the key, run:

slmgr /ato

This command initiates an attempt to activate the system through Microsoft's servers. If everything is properly configured, the activation will be completed successfully.

4. If Necessary, Check License Details

To display basic license information, use:

slmgr /dlv

The command shows activation details, licensing channel, and the status of installed keys. This is the most convenient way to confirm whether ESU Year 3 has been added correctly.

5. Restart the Computer

After activation, it's a good idea to restart the computer and then check if the system properly recognizes the extended support and can download the relevant updates.

Verification

After completing the activation, it's best to perform a brief verification.

Use the command:

slmgr /dlv

Pay attention to:

  • license status,
  • activation information,
  • the presence of a properly installed ESU add-on,
  • the absence of error messages.

You can also run:

slmgr /xpr

This command shows whether the activation is valid and what its status is. If the system reports the activation correctly, you can proceed to Windows Update and check for the availability of security updates.

In practice, successful activation of ESU Year 3 means that the computer meets the continuous licensing requirements: Year 1 + Year 2 + Year 3. The Year 3 key itself does not activate the program from scratch, as it is an add-on to the previous years of support.

Problems

The most common issues with activating Windows 10 ESU Year 3 are not due to the key itself, but rather the lack of meeting the preliminary conditions.

Lack of activated ESU Year 1 or Year 2

This is the most common cause of failure. ESU Year 3 requires prior activation of Year 1 and Year 2. If any of these stages are skipped, the activation of the Year 3 add-on will fail.

Incorrect system edition

Not all editions of Windows 10 support the same ESU licensing model. If the system is not compatible, slmgr /ipk may accept the key, but the activation slmgr /ato will end with an error.

Lack of system updates

Windows 10 should have the required updates installed to support ESU. If the computer has not been updated for a long time, first run Windows Update, and then try to activate again.

Problem with internet connection or activation server

Online activation requires a connection to Microsoft services. If an error occurs with slmgr /ato, check your internet connection, firewall settings, and ensure that the system has the correct date and time.

Typo in the key

It's worth pasting the key carefully and ensuring that there are no spaces at the beginning or end. Even a small error will cause the key to be rejected or display an incorrect installation message.

If after performing all the steps the activation still fails, please contact us: [email protected] or call 00 800 121 1654.

FAQ

Can ESU Year 3 be activated without Year 1 and Year 2?

No. ESU Year 3 is an add-on and requires prior activation of ESU Year 1 and ESU Year 2. Without this, the system does not meet the licensing conditions.

What command is used to activate the ESU Year 3 key?

First, you install the key with the command:

slmgr /ipk YOUR-KEY

Then, you run the activation:

slmgr /ato

How to check if ESU Year 3 is working correctly?

It's best to use:

slmgr /dlv

and:

slmgr /xpr

This will allow you to check the license status and confirm that the activation was performed correctly.
