    Error 0x87E10BC6 indicates that Windows is unable to contact the Microsoft activation servers. Here are some steps to troubleshoot and resolve the issue:

    1. Check Internet Connection

    • Ensure your device is connected to the internet.
    • Try opening a website to verify connectivity.
    • If using a proxy or VPN, disable it temporarily and try activating again.

    2. Run Windows Activation Troubleshooter

    1. Open Settings (Win + I).
    2. Go to System > Activation.
    3. Click Troubleshoot and follow the instructions.

    3. Manually Activate via Command Prompt

    Try activating Windows using the command line:

    1. Open Command Prompt as Administrator (Win + RcmdCtrl + Shift + Enter).
    2. Run the following command to force activation:
       slmgr /ato
      
    3. If that doesn’t work, try re-entering your product key:
       slmgr /ipk YOUR-PRODUCT-KEY
      
    4. Then activate again:
       slmgr /ato
      

    4. Check Date & Time Settings

    • Incorrect system time can interfere with activation.
    • Go to Settings > Time & Language > Date & Time and enable Set time automatically.
