I am the only one using my computer. In the Documents and Settings I see
a folder with my name, plus the folders All Users, Default User, Owner.
Do I need all these?
Mostly.
The "All Users" profile is used to ensure that systems settings and
most application shortcuts are available to any and all current and
future user profiles created on the computer, without there being a need
to duplicate those settings and shortcuts in each and every user account
created on the computer. In the long run, the presence of this profile
generally safes hard drive space by placing commonly used used settings
and shortcuts in a central location. The "Default User" profile serves
as the template for each new user account as it's created, and as a
foundation for all existing profiles; if it could be deleted, it would
render all users' desktops blank. (This also sometimes happens when a
hard drive error causes the profile to become corrupted, as well.) The
OS is designed to function with these profiles, removing them would
render your computer unusable.
The "Owner" profile, however, is probably not essential, unless you're
actually using it. (It doesn't sound like you are.) While there's no
hard and fast rule, this profile is usually created by the computer
manufacturer for use by the first person who uses their OEM
installation. In general, once you've created user profiles for your
own use, this profile can be deleted.
Why not have a single one?
Because that's not the way a multi-user OS works. It's simply more
efficient, this way. For more detailed technical explanations, consult
Microsoft.
Also, how can I change my profile name?
You can't.
The user profile folders (C:\Documents and Settings\Username)
_cannot_ be renamed, even if the associated user account has been.
So, your best course of action would be to log on using the built-in
Administrator account, create a new user account, with the username
desired. You can then delete the old user account(s).
