Awesome sub-forums
May be good to include uninstallers.
I recommend CCleaner on Windows.
I don't know how to do uninstallation on Linux. Someone may wanna shed light on that one
sudo apt-get remove [package name]
Also, if you want useless dependencies removed, install deborphan or debfoster.
...provided the distribution of Linux you're using uses apt for package management! RedHat, for example, uses rpm's.
If you're a purist like me who downloads the source and compiles it yourself, "make uninstall" typically works from the source's directory.
