Windows XP is a multi-user OS, even when used by one person only, the
fundamentals don't change.
Documents and Settings is the directory that contains your user
information/documents/etc. It also contains a few extra directories used by
One is "Default User" - This is used whenever a new account is created. It
bases the initial setup of that account off this directory.
Another is "All Users" - This is used by.. all users. If you want something
to appear on the desktop of every user of the machine, you put it on this
users desktop (in the desktop folder.) Etc.
You may also see "Administrator" - depending on your setup, this is the
original administrator user and if you know that account's password, you
should leave him alone and use him only in an emergency.
You could also (if you have it where you can see ALL files) see
"LocalService" and "NetworkService" folders. These are service accounts,
normally unused by the standard user.

yourself before you take any advice - you are the one ultimately
responsible for your actions/problems/solutions. Know what you are
getting into before you jump in with both feet.
