Ko te hua, ko nga mema o te kaupapa, i arahina e te kaiwhakahaere Jason Filby, i hono tahi ki te whakaora i te kaupapa. I whai te kaupapa i whakahoutia ki te taarua i nga mahi a Windows NT. I te waihanga i te kaupapa hou, i whiriwhiria he ingoa hou, ReactOS. I tīmata te kaupapa i te Hui-tanguru 1998 mā te waihanga i te pūtake mō tētahi pūmatua NT hou me ngā taraiwa taketake. Ko te ingoa ReactOS i hangaia i roto i te korerorero IRC. I te wa e tu ana te kupu "OS" mo te punaha whakahaere, ko te kupu "whakautu" e pa ana ki te koretake o te roopu ki te <unk> me te urupare ki <unk> te tuunga monopolistic a Microsoft. I te tau 2002 i whakatuhia te ReactOS Foundation i Moscow me Maxim Osowski me Aleksey Bragin hei kaiwhakahaere whakahaere me Vladimir Bragin, Saveliy Tretiakov me Alexey Ivanov i roto i te poari kaiwhakahaere. I te tau 2015, i whakakorehia te turanga.  Pātai: He aha te huarahi i whakatakotoria e ReactOS?
