if you download a program to your hd its like being on a disc, so you need to click on it to install the program into windows. So I guess you could say a downloaded program is a back up if you install it you can delete the original download, just as if you removed a disc from your dvd drive. hope this helps a bit.

I don't understand the above response at all, sorry. But to answer your question, it all depends on how a program is written and the complexity of the specific program. In order to run, many programs need to install .dll and other files into as well as entries into the registry. Some simple programs are "self contained" and require no installation at all - they are ready to run just by clicking on the .exe file. These programs also have no associated uninstaller (since there is nothing to uninstall). To "uninstalll" the program you simply delete the .exe file or the folder that contains it.
