That's the whole point Richard. I have just reinstalled my O/S and I want a listing of what is presently in my registry so I can check to see what has changed. I had to reinstall the O/S because I inadvertently downloaded a Yahoo app. My uninstaller program wiped most of it out but when I checked the registry I found some traces left over which I removed. I also found a number of entries I suspect have been installed by Yahoo but under a code identifier, not a name. Since I won't delete anything from the registry that I can't identify, I would like to print out a listing of all items in the registry prior to installing any new apps, after installing new apps, and following the uninstallation of any apps. These unscrupulous entities such as Yahoo, Apple, and Nero like to hide these things so they show up in various UAC windows and other places and, when you have enough of these leftovers in your registry, it tends to slow down your computer. As the Beatles said in Penny Lane: "He likes to keep a clean machine."
