I am uncertain about the reason for such a high level of security. When I installed the operating system on a new SSD, I discovered that numerous files on the same computer’s HDD appear to have no owner. As the current administrator, I am unable to access these files without updating their ownership to a new user or group.

This information is displayed when viewing the Properties of the file or folder:

Although I am able to change the owner of each file individually and resolve the issue, the challenge I face is that there are numerous files (perhaps thousands or more) that require ownership modification. It is impractical to manually right-click on each file, select Properties, and then change the owner to my current account. This task is very daunting.

Could you suggest any helpful tips or techniques to address this problem?
