We install many applications into our system for our purpose and uninstall them when our work is over and if the application is not needed.
But did you know that there are many changes that the application does while installation procedure? Uninstalling the software does not always remove all the files stored by it. The installation utility adds some files to your system, replaces other files, and changes elements of the Registry and essential INI files.
So if next time you want to completely remove a tool from the system just use this tool called Install Tracer. What it does is it provides what the program did and what all changes it made to the system while installation; thereby you can easily delete those files. The tool is quite small in size and can be downloaded from here.
