Not quit sure how to describe this problem.

I re-installed WinXP over an existing WinXP installation.
The original primary user folder in Explorer was set as Owner. While
upgrading the machine I choose a use name of Art so now I have folders that
look like the following when in WinExplorer and Windows will not let me
change these folder names:

- All.Users.WINDOWS
- Default.Users.WINDOWS
- Owner.ART-4DA19282EE5

My question:
How do I change the folders back to what they were originally:
- All Users
- Default User
- Owner
