  • 1Identify the activation error or message

    Select the message or error code you see when trying to activate Windows.

    What do you see?
  • 2Check Windows edition vs license type

    Activation fails if the installed edition does not match the license.

    Which edition is installed?
    What type of license do you have?
  • 3Check Microsoft account & digital license

    Digital licenses require your Microsoft account to be linked to the device.

    Is your Microsoft account linked?
  • 4Run the Activation Troubleshooter

    Windows includes a built‑in troubleshooter for activation issues.

    What happened when you ran it?
  • 5Validate your product key source

    Activation often fails because the key is invalid, blocked, or mismatched.

    Where did your key come from?
  • 6Check for recent hardware changes

    Major hardware changes (especially motherboard) can break activation.

    Did you recently change hardware?
  • 7Advanced activation commands (SLMGR)

    These commands help diagnose activation status.

    Are you comfortable using Command Prompt as Administrator?
    If yes, run these commands:
    slmgr /dlv

    slmgr /ato

    These commands show activation status and attempt activation.
