Quite few of the bigger OEMs system set ups were similar, having 3rd party tools as well as tutorials included in the default installation.. Maybe that could be another thread on it's own. Amstrad for example shipped systems in 1990 with Counterpoint.
It had a tutorial built in and dos utility assistace
Compaq shipped TabWorks with their systems. HP had a very nice nice Dos menu with tutorial included. Windows really didn't be come relevant in the market place until 3.0 was shipped. Then 3.1 bundled with systems. Though Zenith supported MS with the project from the early days.
And of course prior to 1990 IBM/MS were pushing MCA and OS/2 as a replacement for Dos. Most of the industry ignored them apart from implementing vga. MS didn't want to continue the 286 OS/2 support which IBM wouldn't agree to and the the famous lovers break up. IBM saw their error and released the PS/1 and PS/ValuePoint lines to grab back some of the market share.
There's a glitch in the matrix.
