Right-click the file or folder and open Properties
By default, the creator of a file of folder in Microsoft Windows 7 is the owner of that file or folder. As owner, that user can allow or deny access to non-administrator users. However, there are times when an administrator, or a user with administrator privileges and/or Take Ownership permission, will want to take ownership of a file or folder.
If you are an administrator, or otherwise have the proper privileges, you can change ownership with these steps:
1. Right-click on the file or folder to get the context menu and then click the Properties menu item.
