"user" security issues with Win2k Pro and Win XP Pro?

with all the new security issues for M$ OS's,
Office Products, and especially I.E. ...


1. i see you can still be a "power" user under
Win 2000 Pro, but i don't see it as a choice
under Win XP Pro

does anyone know of security issues with being
a "power" user when surfing the web with Win 2000?

(vs. being a more restricted "normal" user)


2. what about "fast" user switching being on/off?
(a choice under Win XP Pro)

"If you select this option (i.e. "on"), programs
do not shut down when another user logs on to
the computer. For example, if you are typing
a report and your child wants to check e-mail,
you can log off using Switch User, the child
can log on, check e-mail, and then log off.
You can log on and return to your report
without losing your place.

Important

When Fast User Switching is turned on, Serial Keys
will not work. Serial Keys is an accessibility
feature that provides support so that alternative
input devices (such as single_switch or puff_and_sip
devices) can be used in place of the computer's
standard keyboard or mouse."


any and all thoughts on 1/2 above, and anything
else on how to minimize chances of an attack
while on the web are welcome (by me)

on XP Pro, my current user ID is a "limited account"

that idea showed up quite a few months ago by
either chrisv or The little lost Angel,
and i finally got off my butt this morning
and am now surfing the web as a limited user

on a side note, will the new Win Vista really help
minimize web browsing risks?

or is it still too early to tell?

i mean, the acid test is when it (Vista) finally
gets released into the cold cruel world.

on a side note, i've moved to a two monitor setup.
last time was on a Sun Unix platform in '97

wow, is this grrrrreat or what?

using a cheap nVidia 6600GT, with an 19" CRT
(that does 1600x1200 ok) and a 20" LCD that
also does 1600x1200 ok. in Dualview, one
of several 2 display options within nView
(clone, horizontal span, and vertical span
are the others)
