RE[5]: Technical detail

Windows 3.1 still relied upon DOS very heavily. It wasn't until Windows For Workgroups 3.11 that brought over some of the 32bit features that were in Windows 95. WFW 3.11 still required DOS for a few DOS drivers like CD-ROM and SCSI support. It was considered just an operating environment because DOS was required to be installed(and booted) first before you could install(and boot) Windows 3.XX.

The same could be said for Win95

Not really. The Windows 95 boot sequence may look the same as DOS, it is actually quite different. IO.SYS in Windows 95 is 32bit and has CONFIG.SYS and AUTOEXEC.BAT commands built-in. IO.SYS is in charge of loading MSDOS.SYS(a text file with boot option flags) and the Registry. CONFIG.SYS and AUTOEXEC.BAT are optional in Windows 95(because the commands are already built into IO.SYS) and can be used to load 16bit DOS drivers if a Windows 32bit driver doesn't exist. Lastly IO.SYS automatically loads(unless you tell it otherwise) WIN.COM.
