WEP

From Minesweeper Wiki

Minesweeper was released 8 Oct 1990 when Microsoft published the first Windows Entertainment Pack. WEP was the first set of games developed specifically to run in Windows rather than in DOS. There were four issues:

1990, Vol.1:	Cruel, Golf, IdleWild, Pegged, Taipei, Tetris, TicTactics, Minesweeper
1991, Vol.2:	Freecell, IdleWild (again), Jigsawed, Pipe Dream, Rattler's Race, Rodent's Revenge, Stones, Tut's Tomb
1991, Vol.3:	Fuji Golf, IdleWild (again), Klotski, Life Genesis, SkiFree, Tetravex, TriPeaks, Wordzap
1992, Vol.4:	Chess, Chip's Challenge, Dr. Black Jack, Go Figure, Jezzball, Maxwell's Maniac, Tic Tac Drop

WEP introduced the game but it was another two years before Minesweeper gained international recognition when it came bundled with the release of Windows 3.1 on 6 Apr 1992. Microsoft has continued to release Minesweeper with new editions of Windows. In 1994 the most popular WEP games were collected and sold as BOWEP.
