However, the harsh reality is that only a small percentage of the uninstaller utility of programs does this task efficiently. When you uninstall a program using its uninstaller utility, it should remove all traces of the program from the registry. Each time you install a new program on your computer or add a file, information about the same is written on the registry.

This takes time, and slows down your computer significantly, especially if it is highly fragmented.Īlthough the Windows operating system contains a defragment utility that ought to put the files in a sequential manner on the HDD, it rarely does the task efficiently, slowing down your computer significantly. When you try to access that file in the future, the read/write head of the hard disk drive has to move to different sectors of the HDD to gather bits and pieces of the file before rendering it.

If the size of the file is bigger than that space, it writes the remaining portion of the file in another sector.

The next time you install another program or store files, they get stored in the first empty space (sector) available in the HDD. When you delete files or uninstall a program, it leaves an empty space on the computer's hard disk drive HDD. When you install a program in a newly configured computer, it writes the information in a systematic way on its hard disk drive.
