Try this activation path for Windows 11 Pro:
- Check activation status in Start > Settings > System > Activation.
- Make sure the device is connected to the internet. Windows activation requires an internet connection.
- Run the Activation troubleshooter:
- Go to Start > Settings > System > Troubleshoot.
- The Troubleshoot option is available only when Windows is not activated.
- Sign in with an administrator account before running it.
- If the device has a digital license but is not activated, in the troubleshooter select Activate Windows, then select Activate.
- If there was a significant hardware change such as a motherboard replacement, use the reactivation flow for hardware changes. A digital license is associated with the device, and major hardware changes can prevent Windows from finding the matching license.
- If online activation still fails, use offline activation:
- Open Command Prompt as administrator.
- Run
SLMGR /dtito get the Installation ID. - Go to the Product Activation Portal, submit the Installation ID, and get the Confirmation ID.
- Back in Command Prompt, run
SLMGR /atp <enter your Confirmation ID>. - Verify with
SLMGR /dli.
- If none of these steps work, use Get help with Windows activation errors or contact support.
Note: SLMGR changes activation state. Enter the Confirmation ID exactly as returned, without <, >, hyphens, or spaces.
