Released October 6, 1988, MS-DOS 4.0 is the forgotten DOS. As such, modern hobbyists are often curious about it. Why did so few people use it?
It was eagerly anticipated and was years in the making, so it’s fair to say DOS 4 was a letdown. It’s a misnomer to say no one shipped PCs with it and no one used it, just like it’s a misnomer to say no one used Windows Vista. But it’s very apt to compare DOS 4.0 with Windows Vista and there were very valid reasons to avoid it in the 1988-90 timeframe. It’s also fair to be curious about it.
