    For Windows 11, the supported ways to find the Installation ID are:

    1. Open Start.
    2. Type Command.
    3. Right-click Command Prompt and select Run as administrator.
    4. Type SLMGR /dti and press Enter.
    5. A Windows Script Host dialog displays the Installation ID.

    If the device is on Windows 11 builds 26200.8973, 26100.8973, and newer, this method is also available:

    1. Open Start.
    2. Go to Settings > System > Activation.
    3. Select Automated Help.
    4. The Installation ID is displayed on the screen.

    If using SLUI 4 on newer Windows 11 builds, it may no longer provide the expected activation experience or be available. Use Automated Help or SLMGR commands instead.

    Have you looked at Settings>System>About? See if what you are looking for is there.

    Hello,

    Could you please confirm whether you are referring to the Windows Product Key used for activation or the Device ID?

    If you are looking for the device ID (unique identification number assigned to your device), go to Start > Settings > System > About > Device info.

    However, the product key is different and is used to activate your Windows edition.

    If the product key is preinstalled with your device (OEM) Motherboard, run the command below in Terminal (Admin) to locate the 25-character product key.

    (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

    You should be able to see the product key installed on your device.
