OK, you've got me interested. What is the threat that UAC mitigates, and is
there any other way to deal with it?
UAC does *not* attempt to authenticate the user in any way, shape or
form as configured out of the box. UAC is entirely about AUTHORIZATION,
not about AUTHENTICATION.
(That being said, with group policies you can set UAC to request a
password before elevating, or you can simply run as a limited user, in
which case UAC will require administrative credentials to be provided
before elevating)
Okay, with that out of the way, what are we authenticating?
Well, in short, UAC is a way of running as a limited user rather then an
administrator. This prevents an application from compromising your
system, and instead limits the application to compromising your data.
Sony's various rootkits for example, would generate a popup before
installing. Web browsers (especially IE, since it uses "Protected
Mode", which is even more isolated) and other apps which process
externally supplied data are especially susceptible to buffer overruns,
UAC effectively prevents a buffer overrun in your browser from being
able to launch code that modifies system settings, or otherwise digs
very deep into your system.
(Actually, UAC doesn't really do much of that. Running as a limit user
does the trick. UAC also allows applications to write to certain areas
of the drive without permission, but those changes are virtualized, so
that when a different user logs in, those changes don't exist)
Also, when Windows defender blocks a
program from the quick launch bar, how can I get it to stop doing that? The
particular program it was giving me a hard time with was Palm Hotsync, which
lets me sync my palm TX handheld with both Outlook and Dataviz Documents To
Go. I use these on a daily basis in my work, and do not have time to spend
hours trying to convince a recalcitrant computer that it can let that program
boot normally.
Palm needs to get it's head out of 1995 and fix their crapware. And I
say that as a very loyal Palm user (Owner of one or more IIIe, IIIxe,
m505, Zire71, TE2, TX, LifeDrive, Treo 650 and Treo 680 devices over the
years)
There are a few tricks to getting HotSync mostly working, but as far as
I know, you will likely never get the installers (Quick or Original)
working. The biggest thing is to never, ever, EVER, Hotsync while a
Palm installer is running, or immediately after. After installing
anything at all Palm related, shut down Hotsync, and restart it.
Secondly, Dataviz's software won't run properly at all, although rumour
has it that Palm's beta Vista compatible Hotsync, plus DTG10 will get
you working. I haven't bothered, I simply installed DTG10 on my PDA
directly and I move files back and forth using SD cards, and/or email,
rather then HotSyncing this data.
