Hi, Michael Dyment
A spinning update screen usually means Windows cannot complete the scan or download, often because of limited storage, a problem update, or incompatible connected hardware.
Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:
Check the free space on drive C under Settings > System > Storage. Use Cleanup recommendations to remove safe temporary files. Windows needs sufficient space to download and prepare updates. Free up space for Windows updates
Disconnect nonessential devices, including printers, external drives, USB hubs, scanners, and docking stations. Keep only the keyboard, mouse, and display connected, then check for updates again.
Open Settings > Windows Update > Update history and look for a failed update and its KB number, such as KBxxxxxxx. Search that number in the Microsoft Update Catalog, download the package matching your Windows version and system type, then install it manually.
If this is a feature-version update, try the Windows Update Assistant. It can install a compatible feature update without waiting for the normal update scan.
If possible, share the Windows version and any error code shown in Update history.
Thank you for your patience in reading, I hope this information has been helpful to you.
