Related systems {{#invoke:main|main}} Several similar products were produced by other companies. In the case of PC DOS and DR DOS, it is common but incorrect to call these "clones". Given that Microsoft manufactured PC DOS for IBM, PC DOS and MS-DOS were (to continue the genetic analogy) "identical twins" that diverged only in adulthood and eventually became quite different products. Although DR DOS is regarded as a clone of MS-DOS, the DR DOS versions appeared months and years before Microsoft's products. (For example, MS-DOS 4, released in July 1988, was followed by DR DOS 5.0 in May 1990. MS-DOS 5.0 came in April 1991, with DR DOS 6.0 being released the following June. MS-DOS 6.0 did not arrive until April 1993, with Novell DOS 7, DR DOS' successor, following the next month.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>) What made the difference in the end was Microsoft's control of the Windows platform and their programming practices which intentionally made Windows appear as if it ran poorly on competing versions of DOS.<ref name="undocumenteddos" /> DRI had to release interim releases to circumvent Windows limitations inserted artificially,<ref name="undocumenteddos" /> designed specifically to provide Microsoft with an unfair competitive advantage.<ref name="undocumenteddos" />

These products are collectively referred to as DOS. However, MS-DOS can be a generic reference to DOS on IBM-PC compatible computers.
