Windows.old directory
So I have noticed that the windows feature upgrades create a Windows.old directory and when you try to delete it, the system pops up an error stating some files are in use. Windows is not using up twice as much hard drive space. 25GB+- for the Windows Directory and 25GB+- for the Windows.old directory. Is there a reason for this? Is there a way to delete this directory. is this going to be the expected configuration going forward for Feature update? - Currently on 1809. thanks
