After upgrading to the operating system, the folder appears on the system partition Windows.old in which they are stored folders and files of the old operating system from your PC / laptop.
In most cases this folder is not used. Windows.old help his user returns to the old version of the operating system if he wants this in time. From our experience, this happens in very few situations, and when a user decides to do one downgrade, it does with a "clean" reinstallation of the operating system.
Normally, this folder will be automatically deleted by Windows after a period of time, but until then, he does nothing but to occupy a considerable space on the disk. And if we have one SSD whose space is quite limited, then maintaining the folder Windows.old is not a good idea.
Being associated as a SYSTEM, its manual deletion is impossible. As long as it does not belong to any user on the operating system, it cannot be deleted by simply selecting and pressing the key "Delete". So we need to assign them special permissions then we can delete it manually. Otherwise we will hit the message "Folder Access Denied".
