It is following the windows dev guidelines for where to put
application data which should not be user visible but may need to be
persisted across sessions.
This would conceptually be %APPDATA%\CompanyName\AppName but in fact
should be located in code by the Shell32 api SHGetFolderPath().
I do not know if this respects changes to the environment variable (I
doubt it - though screwing with the registry might work).
If you can handle it security wise is is probably ok to give all local
users the relevant rights this area. Better still would be to
pre-create the MathWorks\MATLAB directory for the default user and
give all local users Create Folders/Append Data rights. (this assumes
you can pre-setup all your submit machines)

Basically it's a perms thing. By default I do not know if XP gives
Everyone the perms required.
On my machine "Everyone" does not have Create Folders/Append Data nor
Create Files on the root of AppData in Default User (nor for that
matter in a random selection of the sub folders that exist). My perms
may not be the defaults however.
You may be able to run matlab in a way that doesn't try to write the
data it is trying to store (again I have no idea how). using
RunAsOwner with the relevant credential setup should also fix it since
you should stop using the Default User directory...
