Another thing to remember is that SOME software will require that the user
be an Administrator. (new version of Internet Explorer) If this is the case
you may NEED to deploy software to computers, as opposed to users. (you
could additionally configure the setting to install software to users with
elevated privileges.) However, installing to computers is a more secure
option.
To reiterate: make sure that your AD Design ALWAYS facilicitates deploying
software to both Users AND Computers, or you will regret it down the line
and will end up adding hundreds of computers to custom groups and filtering.
