Sequential differential backups sometimes smaller in size.
I recently installed Aomei Backupper Pro 4.1.0 and am using the space disk management scheme. Sometimes the file for a differential backup is smaller then the previous differential backup. How is this possible?

Maybe windows.old, the previous version of Windows10 kept for a few weeks after a big Win10 update. After a few weeks,and you did not rollback, the windows.old is deleted automatically.
