Microsoft Corp. has named Satya Nadella, head of its cloud computing business, as the company’s next CEO. He immediately replaces Steve Ballmer, who had announced in August that he would retire from the world’s biggest software company after more than 13 years at its helm. Here’s a look at key moments in Microsoft’s history.

- 1980: Ballmer joins the company.

- 1981: IBM ships first personal computers running MS-DOS operating system.

- Nov. 20, 1985: Microsoft ships first version of Windows, more than a year after Apple came out with its Mac computer with a graphical user interface and a mouse replacing keyboard commands.

- 1992: Nadella joins the company.

- Aug. 24, 1995: Windows 95 is released in one of Microsoft’s biggest product launches ever.

Ballmer vows to put more money into research and development of search technology at Microsoft.

- May 4, 2006: Ballmer says MSN Search, Microsoft’s search engine, is gaining steam against rivals, but still trails Google and Yahoo.
