Not quite. It says there ....
1. Right-click the folder that you want to take ownership of, and then click Properties.
2. Click the Security tab, and then click OK on the Security message (if one appears).
3. Click Advanced, and then click the Owner tab.
There is no Security tab on the Properties screen, so I can't follow those instructions.
Anyway I got the answer to this in the eldergeek.com forums. Someone was kind enough to write out what to do, instead of just pasting a link.
