Basic maintenance software or utility programs can be found in the Operating System itself. Disk Cleaner and Disk Defragmenter are available as preinstalled utility programs. There are some other external programs such as disk partitioning (Norton Ghost) and files retriever (Lexar Image Rescue).

The installation steps are similar to that of application software for external programs.

These are examples of Window's integrated Disk Cleanup and Disk Defragmenter.
