    To activate Windows 10 using the Installation ID, you need to follow these steps:

    1. Open an elevated Command Prompt: You can do this by searching for "cmd" in the Start menu, right-clicking on Command Prompt, and selecting "Run as administrator".
    2. Run the command to get the Installation ID: Use the following command, replacing <Activation ID> with the actual ESU Activation ID you have: 
         slmgr.vbs /dti <Activation ID>
      This will display the Installation ID.
    3. Call the Microsoft Licensing Activation Center: Use the Installation ID to call the Microsoft Licensing Activation Center for your region. They will guide you through the process to obtain the Confirmation ID.
    4. Activate with the Confirmation ID: Once you have the Confirmation ID, run the following command in the elevated Command Prompt, replacing <Confirmation ID> with the ID you received: 
         slmgr.vbs /atp <Confirmation ID> <Activation ID>
    5. Verify the activation: To check if Windows 10 is activated, you can run: 
         slmgr.vbs /dlv
      This will show the license status and confirm if it is licensed.

    These steps will help you activate Windows 10 using the Installation ID and Confirmation ID.

    Hello KAUSTAVE DAS

    Windows activation cannot be completed with only the “Installation ID.” That identifier is part of the phone activation process, but it must be paired with a “Confirmation ID” that is generated by Microsoft’s activation servers. The supported procedure is to open the activation wizard (slui.exe 4), select your country, and call the Microsoft activation phone number provided. You will be asked to read the Installation ID, and Microsoft will return the Confirmation ID, which you then enter to complete activation. Without that Confirmation ID, the Installation ID alone has no effect.

    If you are working in a volume licensing environment, activation is handled differently: either through a KMS host or Active Directory‑based activation, and in those cases you do not use Installation IDs at all. For retail or OEM licenses, the phone activation method described above is the only supported way to use the Installation ID.

    I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

    Harry.
