Many Microsoft applications were clearly best of breed. Yes, nasty, underhanded tricks were used to make those products dominant. But many Microsoft products from Excel to Internet Explorer really were superior to their direct competition at the time. Particularly when measured by the criteria that Microsoft was trying to win by - ease of development for third parties and ease of use.
That didn't happen by accident.
It didn't always happen either. For instance their operating systems often were not as good as the competition, but they weren't trying to be either. They already had a monopoly and their goal was to extend it, which gets in the way of a quality product.
But whatever their goals were, for a long time Microsoft hit them very reliably. That requires talent, discipline, and a solid organization. Never let your dislike blind you to their strengths.
Cheers,
