    Can you please type cmd in the search on the taskbar and hit enter to launch command prompt, then run the following command:

    slmgr /dlv
    

    Then share a screenshot please. Thanks!

    If you are unable to activate Windows 11 after changing security features in the BIOS, here are some steps you can take:

    1. Check Activation Status: Go to Settings > Update & Security > Activation to see the activation status. If it indicates that Windows is not activated, you might need to troubleshoot further.
    2. Ensure Secure Boot is Enabled: Since you mentioned that you had to enable Secure Boot, double-check that it is still enabled in the BIOS/UEFI settings. Sometimes changes can revert, or settings may not save correctly.
    3. TPM Settings: Make sure that TPM (Trusted Platform Module) is enabled as well. This is often required for Windows 11 activation.
    4. Run Activation Troubleshooter: In the Activation settings, you can find an option to run the troubleshooter. This can help identify and fix common activation issues.
    5. Check for Updates: Ensure that your Windows 11 installation is fully updated. Sometimes, pending updates can affect activation.
    6. Contact Microsoft Support: If none of the above steps work, you may need to reach out to Microsoft Support for assistance with activation issues.

    By following these steps, you should be able to resolve the activation issue with Windows 11 after modifying your BIOS settings.
