While not every program that posses a threat to your PC will attempt to write changes to your Windows registry, an awful lot will. So one way to keep your computer healthy is to track any changes to your registry. RegRunner is a free utility that hangs out in your system tray until a registry change is made, and then it pops up to let you know that something's going on. In other words, if you install and uninstall software on regular basis, RegRunner could be just as annoying as the user account control pop-up in Windows Vista. But just like the UAC, RegRunner can also prevent you from doing anything too foolish.
RegRunner also has a couple of other useful features. It will show you a list of programs that load when Windows starts. Another tab shows running processes.
The program does not include an uninstaller. If you want to remove RegRunner from your system, you'll have to delete installation directory and the shortcuts from the Startup folder in your Windows start menu.
