Eminyakeni eyishumi ngemuva komthombo ovulekile we-MS-DOS 10 kanye ne-1.25, iMicrosoft yamemezela umthombo ovulekile wesistimu yokusebenza ye-MS-DOS 2.0, eyakhishwa ekuqaleni ngo-4.0 futhi yathuthukiswa ngokuhlanganyela ne-IBM. Ikhodi ivuliwe ngaphansi kwelayisensi ye-MIT, ekuvumela ukuthi uguqule ngokukhululekile, usabalalise futhi usebenzise emikhiqizweni yakho. Ngaphezu kwekhodi, amadokhumenti nezithombe zediski zitholakala esidlangalaleni.
Umkhiqizo ubhalwe ku-assembler yama-8086 processors kanye nama-emulators angama-86box angasetshenziswa ukuwuqhuba. Ukukhishwa kwe-MS-DOS 4.0 kuyaphawuleka ngekhono lokusebenzisa isixhumi esibonakalayo negundane, ukusekelwa kwezingxenye zediski ezinkulu kuno-32 MB (kufika ku-2 GB), ukungezwa kwemenenja yefayela ye-DOSSHELL, ukusekelwa kwe-EMS (Ukucaciswa Kwenkumbulo Enwetshiwe ), FASTOPEN kanye nemiyalo ye-FASTSEEK.
