That is equally true according to your definition of > "runs on top of" - but it's not a useful statement. You should try to read the Wikipedia entry <en.wikipedia.org/wiki/Windows_95> <Quote> To end-users, MS-DOS appeared as an underlying component of Windows 95. For example, it was possible to prevent loading the graphical user interface and boot the system into a real-mode MS-DOS environment. This sparked debate amongst users and professionals over the question of to what extent Windows 95 was an operating system or merely a graphical shell running on top of MS-DOS. From an architectural stance, both viewpoints lack nuance. When the graphical user interface was started, the virtual machine manager took over the filesystem-related and disk-related functionality from MS-DOS, which itself was demoted to a compatibility layer for 16-bit device drivers.[14] This contrasted with earlier versions of Windows which relied on MS-DOS to perform file and disk access. (Windows for Workgroups 3.11 could also largely bypass MS-DOS when 32-bit file access and 32-bit disk access was enabled.) Keeping MS-DOS in memory allowed Windows 95 to use DOS device drivers if suitable Windows drivers were unavailable. MS-DOS also still handled most other functions (for example, allocating memory and parsing file names), issued by legacy Win16 and DOS applications, as Microsoft saw little benefit in replacing these helper functions with newly-written 32-bit code.[14] <Unquote> -- Best regards, * Klaus Meinhard * <www.4dos.info>
