Microsoft
Microsoft's first operating system named Windows was introduced on November 20, 1985. The Microsoft Windows operating system is now available in 137 languages.
Microsoft makes software, not computers. International Business Machines, better known as IBM, invented the IBM PC, which much of Microsoft's software is designed for and is the type of computer you mean. It was first released in 1981. Microsoft provided the operating system, known as DOS (Disk Operating System). In subsequent years they released newer versions of DOS and eventually the various Windows operating systems that we use now, as well as other software that we use such as the Microsoft Office programs.
Windows 95 was the "first Microsoft Windows operating system" released on August 24, 1995. The "first Microsoft Operating system" was DOS 1.0. Windows 1.0 up to 3.1 were all operating environments. That is software that acts as an operating system, but need an operating system to boot in this case DOS. The answer to your very specific question is Window 95 that was released on August 24, 1995.P.S. Windows 95 was also the first Windows to utilize Plug and Play. (PnP)
