Like when you do the UNINSTALL program feature, some program leave behind ghost files or system files of previous installs. How can I get rid of those as well and remove all traces of uninstalled programs?
What BB said. Most programs leave DLLs and other crap regardless.
This is why I occasionally formatt and re-install the OS.
There is an application that will watch every install and where and what is installed.
When you want to de-install something do in in Windows and again in the utility and every file will be removed.
I forget the name.. Install magic or something like that
