Windows 1

Windows 1/1.0 Is The First Operating System Microsoft Had Released. It Achieved A Little Popularity. It Wasn't A Real Operating System In Cause It Was Half MS-DOS Based It Seemed More Like An Operating Environment. You Could Control The Operating System With The Mouse And Keyboard. Further It Contains Some Simple Applications. I Don't Know Much About Windows 1, So If You Know Something About This I Don't, Add It Here by Editing The Page.
