Why We Need Uninstaller Software...
When a program or software is installed on a computer system there will be more than just one file created. These files are important for the application to run successfully and they consist of configuration files, registry entries, environment variables and log files. The Registry entries act as a data base and stores the entire configuration for the software. It also used to synchronize the software process between the other processes. Configuration files will have the initial settings for the software to run or launch successfully. Some applications will use these files only when the software is launched or started and few will access it at the time of exit to check whether there are any changes in the settings. Environment variables will define the exact environment for the software to run successfully. It defines the path for the files and folders like temporary files etc… These are the volatile values which changes frequently when the program is under execution. The log file will store the overall information relating to when the software is installed, any changes that occur in the registry files, configuration files and so on.
Need For Removal Software
Till now we just used to double click the setup file of the software and sit quietly until the installation was successful. It is very easy from the user point of view. In the same way when we want to uninstall the software, we go to ‘Add or Remove’ programs and uninstall it. Even uninstalling is a simple task but after knowing the backend work process when software is installed, there is a good chance that there will be many leftover files if you remove the software. Today’s software applications are so big and therefore, when it is installed it creates a whole lot of additional files and folders. When it is executed each and every time, registry files, configuration files, environment variables and log files will be changing. Using a paid or free uninstaller program can help you completely uninstall programs from your operating system and also get rid of those unwanted leftovers.
You see, if there are drastic changes in the log file itself, the ‘Add or Remove’ feature will be guided in a wrong way to uninstall a program. This is why, most of the related files of the supposedly uninstalled software will still reside in the system even after successful uninstallation. Also it is very difficult for the users to search for these sorts of data and delete them manually. Even system administrators who have strong knowledge of the operating system struggle to figure out where these files reside in the system. This is why it is helpful to use any available free uninstaller application that can be easily downloaded on the internet.
What Does An Uninstaller Do?
Uninstaller software is used to remove or uninstall programs completely from the system. The removal process done by using this tool will usually delete all the related files from the system completely. As the ‘Add or Remove’ feature depends on the log file to trace the related data and delete while uninstalling, uninstaller tools do not depend on these files. That is why it is possible for it to delete all the related data successfully.
When we initialize a uninstaller tool to remove a particular software , it scans and searches the whole disk to find out where the related files are. When the entire search is done, it will complately remove all the related files of the application and thus your system will be fast and clean from the unwanted files. This is how most paid and free uninstaller programs work and why they are stronger than ‘Add or Remove’ feature of standard operating systems. There are lots of free uninstaller tools available in the market available for download & purchase.
