WinXP was developed mostly during Gates' tenure. Ballmer is responsible for the disastrous Windows Vista, Microsoft phone operating systems, and Windows 8.
You mean the best mobile phone OS that we ever had? Unfortunately disastrously managed and then squandered, but still.
Also, Vista was a mess, but it was ambitious and it laid the foundation for 7 and it was only around for a few years before being replaced. Unlike 10, where Nadella has doubled down on the worst choices and even worse ones were made going into 11 (HOW THE FUCK DO YOU SET DEFAULT APPLICATIONS NOW, THIS IS FUCKING NONSENSE).
