Microsoft has nominated GlaxoSmithKline chief executive officer Emma Walmsley to its board of directors.
The software company said former chairman of the board of management at BMW AG, Helmut Panke, will not seek a re-election to the board after his current term expires.
Charles Noski, former vice chairman of AT&T and Bank of America Corp, is also leaving the board.
The company's annual shareholder meeting is due on 4 December.
Shares of the company were up 1.84 per cent in after-market trading after rising to a record high during the regular trading hours after it announced a $40 billion share buyback plan.
