When you install a program in your Windows 7 computer, some of the files related to that program are copied into the folder related to that program in your Windows 7 computer. The common files like DLL files are also copied if required. Once the files are copied into your computer, and the program ins installed in your computer, some changes to the Windows Registry are made by the installer. The Windows Add/Remove tool searches for this entry in Windows Registry to check for installed programs. All the changes made to the Registry are logged into a file which is also stored in the folder related to the program. This will be useful for the uninstaller to uninstall the program at a later date. Whenever you want to uninstall the program, the uninstaller checks the log file for the changes made during installation and undoes the changes. The uninstaller then removes the copied files and removes the entries in the Registry.
Suppose the log file is not there in the application folder, then it would be very difficult for the uninstaller to uninstall the program. Then what is the way to uninstall a program if you face this kind of problem.
