Frank Shaw, who currently manages the Microsoft account at Waggener Edstrom, will replace Sproule in August as corporate vice-president of corporate comms.
Sproule will return to the automotive industry to take up a role with Renault-Nissan. His new appointment will be based in Paris.
Ali Perkins, head of UK PR at Microsoft said: 'After an unexpectedly brief but successful stint at Microsoft, Simon Sproule has decided to return to his roots in the automotive industry.
Frank Shaw is a veteran PR and communications professional with 20 years of experience. More importantly, he is intimately familiar with Microsoft, our business and our leadership team and will bring stability and valuable perspective to the role.'
