An owner is assigned to an object when that object is created. By default, the owner is the creator of the object. No matter what permissions are set on an object, the owner of the object can always change the permissions.
The owner of an object (ex: file, folder, drive, or registry key) has the right to allow or deny access to that resource. Although members of the Administrators group and other authorized users also have the right to allow or deny access, the owner has the authority to lock out non-administrator users, and then the only way to regain access to the resource is for an administrator or a member of the Restore Operators group to take ownership of it. This makes the file or folder owner important with respect to what permissions are allowed or denied for a given resource.
Ownership can be taken or transferred in several ways. The current owner of an object can transfer ownership to another user or group. A member of the Administrators group can take ownership of an object or transfer ownership to another user or groupâ€”even if administrators are locked out of the resource according to the permissions. Any user with the “Take Ownership” permission on the object can take ownership, as can any member of the “Backup Operators” group (or anyone else with the “Restore Files And Directories” user right, for that matter).
This tutorial will show you how to add Change Owner to the context menu of all files, folders, and drives for all users in Windows 10.
The Change Owner context menu will allow you to quickly and easily see which user or group is the current user of a file, folder, or drive.
The Change Owner context menu will also allow you to instantly change the owner of a file, folder, or drive to Administrators, Everyone, SYSTEM, or TrustedInstaller on demand.
When you right click or press and hold on a file, folder, or drive, click/tap on Change Owner, and click/tap on either one of the the Change Owner to… items, you will be prompted by UAC to approve.
The Change Owner context menu will not be available when you right click or press and hold only on the specific C: drive, C:\Program Files folder, C:\Program Files (x86) folder, C:\ProgramData folder, C:\Users folder, and C:\Windows folder. This was done by design since changing the owner of the Windows “C:” drive and these specific system folders can make Windows unstable as it would also take ownership of all their content at the same time.
You will still be able to use the Change Owner context menu on files and folders inside the locations above, and on all drives other than the C drive and FAT32 drives.
