Windows Users: Drop Your Rights
Security Fix has advised Microsoft Windows users in the past about the
importance of running everyday software applications under user accounts
that do not have the power to install programs or modify the underlying
operating system in any way. The reason is simple: Spyware and other
unwanted programs have a much harder time getting their hooks into your
system if the current user lacks installation privileges.

I have written before about the importance of setting up and using "limited
user" (non-administrator) accounts for everyday Windows users. But many
users balk at the idea, complaining (in many cases rightfully so) that
such-and-such program doesn't work or perform as well under a non-admin
account. (By default, when you first install Windows XP, all of the active
user accounts created are administrator accounts, meaning they have full
rights to install, modify or delete any program, file or system process
running on the computer.)

Such complaints are hardly unfounded. I have been running most of my Windows
PCs under limited user accounts for the past two years or so and have run
into my share of problems trying to get third-party software to play nice
with Windows. Ever since I wrote a column late last year urging Windows
users to reconfigure for limited accounts, hardly a week has gone by when I
haven't heard from some reader who's had problems as a limited user.

For those who feel it is too much of a burden, I'd like to propose another
solution: running your browser, e-mail, and perhaps other regularly used
Web-facing programs each under its own less-privileged account.

Among the easier tools is one provided by Microsoft: DropMyRights. (Weirdly
enough, if you Google "DropMyRights," the first, and legitimate, result is
from Microsoft.com but appears to be some jumbled, foreign language or
perhaps a link to a phishing site.) Security Fix will show you how to modify
the desktop icons you normally click on to access the Internet and your
e-mail account so that they run under less-privileged user accounts, and
thus are less prone to attack.
