You'll need to be explicit about which software packages and which versions you've installed. Some of the packages are, shall we say, less useful than others.
Edited to add:
You might try doing a reset to a recent restore point. It's a reasonably reliable way to undo recent software installations -- usually doing a better cleanup than running the official deinstallers.
