Welcome James Slater,
Thanks for reaching out to Microsoft Q&A Forum. I understand your new PC repeatedly displays a CLiP License Device ID mismatch after you purchased Windows 11 Home from the Microsoft Store.
Before proceeding, could you please confirm:
- What activation status and error code appear under Settings > System > Activation? Does the CLiP error appear during Windows activation, or only when you open a Microsoft Store app?
In addition to the previous suggestions, you could also explore these options:
1, Confirm the installed edition under Settings > System > Activation is Windows 11 Home.
2, Run the Activation troubleshooter.
- Open Settings > System > Activation
- Select Troubleshoot
- If a valid Windows 11 Home digital license is found, select Activate
3, Install all available updates under Settings > Windows Update, restart the PC, and check activation again.
If the answer is helpful, please click "Yes". If you have extra questions about this answer, please click "Comment".
