"Delete programs you never use
Many PC manufacturers pack their new computers with programs you didn't
order and might not want. These often include trial editions and limited
edition versions of programs that software companies hope you will try, find
useful, and then pay to upgrade to full versions or newer versions. If you
decide you don't want them, keeping the software on your computer might slow
it down by using precious memory, disk space, and processing power.
It's a good idea to uninstall all the programs you don't plan to use. This
should include both manufacturer-installed software and software you
installed yourself but don't want anymore-especially utility programs
designed to help manage and tune your computer's hardware and software.
Utility programs such as virus scanners, disk cleaners, and backup tools
often run automatically at startup, quietly chugging along in the background
where you can't see them. Many people have no idea they are even running.
Even if your PC is older, it might contain manufacturer-installed programs
that you never noticed or have since forgotten about. It's never too late to
remove these and get rid of the clutter and wasted system resources. Maybe
you thought you might use the software someday, but never did. Uninstall it
and see if your PC runs faster."
At least one OS publisher packs their Vista OS full of crap that can't be
removed, whether the end user will ever use it or not.
