Windows 7: Two "User" Directories

I've just recovered from a real system mess (not a "crash" exactly, but it seems to have had to do with a corrupted bootup configuration or, perhaps, drive letter slide). Not sure what caused it; not sure which of the many things I did cured it (system restore, system recovery, backup restore, mucking about with Hiren's, etc.), although the last one was use of my Windows 7 System Repair Disk.

Most everything works the way it did a week ago. However, I find I have two "User" directories, one created in 2009, the other created yesterday. Is this a problem? Will it be a problem in the future? How do I fix it?



I started copying the contents of one into the other, but I quickly stopped that when I realized that the bootup files (my bugaboo) were there.

Any advice and intelligence would be welcome. Thanks.
