Windows 10 Windows.old Size Shows Differently Across Tools

WinDirStat shows Windows.old as 200+GB, Disk Cleanup as 700+GB, and File Explorer as 1.0GB. Why the huge discrepancy?

    WinDirStat and Disk Cleanup use various methods to scan the file system, which can lead to differences in reported sizes. WinDirStat scans the file system recursively, while Disk Cleanup uses a different approach that might miss some files or folders.
