It is hard to say exactly what happened. Usually what happens is the user
changes permissions/security settings [or installs a security template]
without understanding the ramifications, the user installs a program that
does such as some of the internet protection/spyware programs have a
"protection" mode that will restrict even the administrators and some of
these programs do not do a good job of warning the user of this, or
malware/spyware has done such. To learn more about the operating system you
may want to purchase a good book on Windows XP. You might want to go to your
local big bookstore to browse the different books on Windows XP to find one
that you are comfortable with as books can either start with the assumption
the users is a total beginner or an advanced user or somewhere in between.
The book below is big but a pretty good book and you don't have to read the
whole thing to learn a lot - just those chapters that interest you. There
are also some great internet resources as shown in the other links and
always try searching Google for a brief description of any problem your are
trying to troubleshoot. --- Steve
