It's possible, possible, you are looking at a windows.old that is empty, but cannot be deleted because the system thinks it's not empty. Common problem, particularly a while back. If you click on it, then next folder you see, then the next, so on and so on, and you get to a point there are no more folders under it, and you get a strange message....that is probably the cause. It is fixable. I/we need to see the pic of your C: directory. Thanks.
Yes, what TC is showing you... let it scan the drive and it shows you what it can remove, Windows installation files are one of the shown options, using check boxes, then the clean button.
Don't be surprised when you run that Storage cleanup if Previous Windows Installations is not listed as an option. That's where the pic of your C: directory will be handy. It can be fixed, if that's the case.
