Fingqa isigaba esilandelayo mayelana ne-Microsoft ngemisho emibili:  IMicrosoft Corporation iyinkampani yezobuchwepheshe yamazwe amaningi yaseMelika ezinze eRedmond, eWashington. Imikhiqizo ye-Microsoft eyaziwa kakhulu yi-Windows line yezinhlelo zokusebenza, i-Microsoft Office suite, kanye neziphequluli ze-Internet Explorer ne-Edge. Imikhiqizo yayo ye-flagship hardware yi-Xbox video game consoles kanye ne-Microsoft Surface lineup yamakhompyutha womuntu siqu. IMicrosoft ibekwe kuNombolo 14 ku-2022 Fortune 500 rankings yezinkampani ezinkulu zase-United States ngenzuzo ephelele; ibingumenzi wesoftware omkhulu kunabo bonke emhlabeni ngenzuzo kusukela ngo-2022. Kubhekwa njengenye yezinkampani ezinhlanu ezinkulu zobuchwepheshe bezokwazisa zaseMelika, kanye ne-Alphabet (inkampani engumzali weGoogle), i-Amazon, i-Apple, ne-Meta (eyayikade i-Facebook).  IMicrosoft yasungulwa nguBill Gates noPaul Allen ngo-Ephreli 4, 1975, ukuthuthukisa nokuthengisa abahumushi be-BASIC be-Altair 8800. Yakhuphuka ukuze ibuse emakethe yezinhlelo zokusebenza zamakhompyutha womuntu siqu nge-MS-DOS maphakathi nawo-1980, yalandelwa yiWindows. Ukunikezwa kwenkampani esidlangalaleni (i-IPO) ngo-1986, nokukhuphuka okulandelayo kwentengo yamasheya ayo, kudale izigidigidi ezintathu kanye nezigidi ezibalelwa ku-12,000 phakathi kwabasebenzi bakwaMicrosoft. Kusukela ngeminyaka yo-1990, iye yahlukahluka kakhulu emakethe yezinhlelo zokusebenza futhi yenze ukuthengwa kwezinkampani eziningana, enkulu kunazo zonke ukuthengwa kwe-LinkedIn ngama- $ 26.2 billion ngoDisemba 2016, kulandelwa ukuthengwa kwabo kwe-Skype Technologies ngama- $ 8.5 billion ngoMeyi 2011.  Kusukela ngo-2015, iMicrosoft ibusa emakethe yezinhlelo zokusebenza ezihambisana ne-IBM PC kanye nemakethe yesoftware yehhovisi, yize ilahlekelwe iningi lemakethe yezinhlelo zokusebenza jikelele ku-Android. Le nkampani iphinde ikhiqize uhla olubanzi lwesoftware yomthengi neyebhizinisi yama-desktops, ama-laptops, amathebhu, amagajethi, namaseva, kufaka phakathi ukusesha nge-Intanethi (nge-Bing), imakethe yezinsizakalo zedijithali (ngokusebenzisa i-MSN), i-mixed reality (i-HoloLens), i-cloud computing (i-Azure), kanye nokuthuthukiswa kwesoftware (i-Visual Studio).
IMicrosoft iyinkampani yaseMelika eyenza isoftware eyaziwa kakhulu ngohlelo lwayo lokusebenza lweWindows, i-Microsoft Office suite, ne-Cloud Computing (Azure), njll phakathi kwezinye eziningi. Yasungulwa nguBill Gates futhi inenani elingaphezu kwezigidigidi zamaRandi.
