When that second user clicks the
Owner tab in the Advanced Security Settings window, the Current owner
may be Creator Owner rather than the actual username of the person who
created the file. No matter; the new user just selects his own username from
the list and clicks OK.
Probably the most you??™ll see of the Creator Owner entry is when you try to
modify a Registry key and Windows won??™t let you until you assume ownership,
close all the Permissions windows, and then reopen them to give yourself
permission to make the change. See ???Prevent Changes to a Registry Key,???
in Chapter 3, for one such example.

Finally, the Effective Permissions tab is a troubleshooting tool that lets you
view the selected object??™s permissions as they pertain to a single user. This is
most useful when dealing with groups of users.
Add new users to the Permissions window
Typically, a single entry, Everyone, will appear at the top of the Group or
user names list in the Permissions window. (Here, Everyone literally means
all users and groups in perpetuity.) More than likely, though, you??™ll want to
eliminate the Everyone entry and add only those users (such as yourself)
whom you need to specifically grant access to your stuff.
Start by deleting any unwanted users by selecting them and clicking
Remove. Then, click Add to open the Select Users or Groups window, as
shown in Figure 8-6.
The first time you use this tool, you??™ll probably expect to see a list of all
the users on your PC; unfortunately, Microsoft in its infinite wisdom
decided it would be easier for you to type each user??™s account name by hand.
