Dick;
The easiest way to change it under Documents and Settings is to create a new
profile and copy the data from old to new profile:

The old profile can be safely deleted from User Accounts once you are sure
all is OK in the new profile.
OK, I got the Registered To: Name entry changed under My
Computer/Properties/General tab, but the original erroneous name entry
appears all over the machine. It shows up in all of the Documents and
Settings paths and therefore is part of every programs data path.
If I search on that bad entry in the registry, it is all over the
place, usually as part of a Documents and Settings path. There must be
50 or more such entries. It even shows up as User Name entries in the
registry even though I never used that as a user name. I suppose I
might be able to change them all (is there a search/replace function
in Regedit?), but what does that do to all the applications that use
the data path with the phony entry? Will they be suitably notified of
the path change by the new registry entries?
This all resulted from a single flubbed key stroke at first turn on,
and now there seems to be no way to recover without major pain.
