To find your Windows 11 installation ID, you can follow these steps:

  1. Use the Activation Troubleshooter:
  • Press Windows + I to open the Settings app.
    • Go to Update & Security (or System in some builds).
    • Click on Activation on the left side.
    • Scroll down and look for the Troubleshoot option. Click on it.
    • Follow the prompts. If it asks for the installation ID, it should display it for you, or allow you to proceed without needing to find it manually.
  1. Using Command Prompt:
  • Press Windows + R to open the Run dialog.
  • Type cmd and press Enter to open Command Prompt.
    • Type the following command and press Enter:
           bash
           slmgr /dti
      
      • This command will display the installation ID in a dialog box.
      Using the Settings App:
      - Open the Settings app again with Windows + I.
      
         - Go to System > About.
      
            - Scroll down to see information related to your Windows specifications, where you might find the ID.
      

Once you have your installation ID, you can provide it to the automated system to proceed with the activation process.

If you encounter any issues, it's also a good idea to check if your Windows activation key is valid and that you're using the correct version of Windows corresponding to your key.

Let me know how it goes.
