Products introduced by MS that were massive commercial failures--neither becoming profitable nor achieving some strategic objective. (MS didn't make money on IE--giving it away--but it certainly shouldn't be counted as a "flop").
- MicrosoftBob
- EuropeanMsDosFour
- MicrosoftChromeFX - Never became a 3d standard, although it arguably achieved the strategic objective of preventing everyone else.
- MicrosoftTest - If you've ever used it, you know why it's a flop
They named one of their fonts "Trebuchet MS". No wonder Windows crashes.
