Activation of Windows 10 ESU Year 2

Windows 10 ESU Year 2 is a security update extension for systems that have ended their basic support period but still need to be used in a corporate or specialist environment. Activating this add-on requires meeting one key condition: Windows 10 ESU Year 1 must already be active on the device. Only then can the ESU Year 2 key be installed and activated correctly as an add-on extension.

Below, you will find a step-by-step guide on how to perform the activation, check its status, and what to do in case of the most common problems.

Step by Step

Before you start, make sure that:

  • your computer has Windows 10 installed and activated,
  • ESU Year 1 activation has been previously performed and completed successfully,
  • you have an internet connection if you plan to activate online,
  • you have a valid Windows 10 ESU Year 2 key.

It is best to perform the activation from the Command Prompt run as administrator.

1. Open Command Prompt as Administrator

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

2. Install the ESU Year 2 Key

Enter the command:

slmgr /ipk YOUR-ESU-YEAR-2-KEY

Replace YOUR-ESU-YEAR-2-KEY with the product key you received.

After a moment, the system should display a message confirming the installation of the key. If an error appears, first check if ESU Year 1 is active on the computer, as Year 2 does not work independently.

3. Activate the License

After installing the key, run the activation:

slmgr /ato

This command attempts to activate with Microsoft servers. If everything is done correctly, the system will return a message about successful activation.

4. If necessary, restart the computer

In some cases, the system immediately saves the new license status, but if you want to be sure, you can restart the computer after completing the activation.

Checking

After activation, it's worth confirming that the license has been accepted correctly. The easiest way to do this is using the slmgr commands.

Basic Status Check

slmgr /dli

The command shows brief license information. You can use this to check if the system sees the activated licensing service.

Detailed Check

slmgr /dlv

This command displays more detailed diagnostic information. It is useful especially when you want to confirm the activation status or identify a problem with the key.

Checking if the System is Activated

slmgr /xpr

The result allows you to check if the activation was performed correctly and if the system or licensing add-on has an active status.

If, after executing these commands, the status still raises doubts, save the message content and contact us: [email protected].

Problems

The most common problem with activating Windows 10 ESU Year 2 results from omitting the requirement of an active Year 1. The Year 2 key is an add-on, not an independent license, so without the prior activation of the first year, the system may reject the installation or activation.

The key will not install

If the command:

slmgr /ipk YOUR-ESU-YEAR-2-KEY

returns an error, check:

  • if the key was entered correctly,
  • if you ran cmd as an administrator,
  • if ESU Year 1 is already activated on the computer.

Activation slmgr /ato ends with an error

First, check your internet connection, and then ensure that the system has installed the required updates and has the correct date and time. An incorrect time configuration can also affect the activation process.

The system displays an unclear license message

In such a situation, run:

slmgr /dlv

Then, save a screenshot or copy the message and send it to [email protected]. This will make it easier to verify whether the problem concerns the key itself, the Year 1 status, or the system configuration.

FAQ

Will Windows 10 ESU Year 2 work without an active Year 1?

No. ESU Year 2 requires an active ESU Year 1. It is an add-on key type, so it only works as an extension of a previously activated license.

What command is used to install the ESU Year 2 key?

To install, use:

slmgr /ipk YOUR-ESU-YEAR-2-KEY

Then, run the activation with the command:

slmgr /ato

How to check if the activation was successful?

It's best to use the commands:

slmgr /dli

or

slmgr /xpr

If the result is unclear, it's also helpful to use:

slmgr /dlv
