Hi Henry Stafford,
Thank you for sharing the details.
If the “Restart required” prompt keeps returning on your Surface Pro 11, it usually means the update did not fully finalize even though the device restarted. Microsoft’s Surface guidance treats repeated pending restart / failed update behavior as an update completion issue rather than a storage-space problem.
In addition to Q&A Assist's suggested steps, please try these extra checks to move forward:
1, Run the Windows Update troubleshooter
- Go to Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run.
- When it finishes, restart the device and check Windows Update again.
2, Disconnect non-essential accessories before updating - remove external drives, docks, adapters, and other accessories, then try the update again.
3, Check date/time and power status - confirm Settings > Time & language shows the correct date, time, and time zone, and keep the Surface plugged in with the battery above 40% while updating.
4, Install any pending optional driver updates
- Go to Settings > Windows Update > Advanced options > Optional updates and install any available Surface or driver updates, then restart once more.
- Surface devices may need both Windows updates and Surface driver/firmware updates to complete successfully.
5, If the built-in diagnostics service is unavailable, use the Surface Diagnostic Toolkit
- From Microsoft Store, install Surface Diagnostic Toolkit, and run the checks it offers for update-related issues.
- Microsoft recommends this tool when Surface is not updating or working as expected.
I hope this helps move the update forward. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
