The majority of computer users install new software on their machines every day. As a result, these same users often find themselves replacing outdated software or switching to new products entirely, and they delete the old software off of their hard drive. Unfortunately, most computer users do not know how to properly uninstall their old software, leading to potential system problems.In most cases, improper software removal can result in pieces of old programs taking up space on the hard drive, although in some cases, the programs cannot even be reinstalled without significant registry modification. With this in mind, it is essential to follow the proper procedures for software removal; most programs cannot simply be removed by pressing selecting their shortcut and pressing the delete key.These issues are largely due to the nature of the Windows registry. The registry is essentially a large database of every piece of software installed on a certain computer. Improper software removal results in the actual files being deleted without removing the corresponding registry entries, leading to a state where the computer believes it has a certain piece of software installed without the corresponding files existing.To correct this, programmers almost always include specific uninstall applications alongside their software. Proper software removal is usually as simple as running the correct uninstall application. Fortunately, when a piece of software is installed, Windows also keeps track of the corresponding uninstall application.By accessing the Control Panel and opening either the Add/Remove Programs (for Windows 9x/XP) or the Programs and Features (for Windows Vista/7) utilities, a user is presented with a list of all the installed software on their computer. The user merely needs to find the specific program they want to remove, select it in the list, and click Uninstall. This launches the corresponding uninstall application, which not only removes all the files associated with that piece of software, but all the registry entries as well.Proper software removal is essential to maximizing one’s available system resources. By merely taking the time to run the correct uninstall application as opposed to just pressing the delete key, a computer user can avoid both registry conflicts and wasted hard drive space.
