WinDOS

WinDOS is an operating system built on MS-DOS 8.0. It is the successor to MS-DOS, and not just has a DOS kernel, but a hybrid kernel containing mostly DOS and some Windows NT code. It builds on MS-DOS with things such as a graphical Windows Preinstallation Environment-like interface, support for Windows NT applications, and multiple user accounts. It also contains basic applications from Windows including: (At startup, it starts at Command Prompt.) WinDOS still has a DOS (disk operating system) functionality, as it is small enough to fit on a floppy disk or CD. It is mainly popular among businesses and people who still have older computers from the 1980s and 1990s.
