Hi, that can happen after a reset, especially if Windows kept recovery files, driver packages, update cleanup files, or a Windows.old folder.
I would check Settings > System > Storage first and open the categories to see what is using the space. Then run Disk Cleanup or Storage Sense and include options like Windows Update Cleanup, Temporary files, and Previous Windows installation if shown.
Also check:
1. C:\Windows.old
2. C:\$WINDOWS.~BT
3. Large files under Downloads or user folders
4. The recovery partition, which will not appear as normal free space
If this is an Insider build, I would be a little cautious before deleting recovery files until you are sure the laptop is booting and updating normally.
