Microsoft said Tuesday it had dismissed chief information officer Stuart Scott for allegedly violating company policies.

Microsoft is remaining tight-lipped about the dismissal. A spokesman for the Redmond, Wash.-based company said Scott was fired on Nov. 2.

Scott's biography on the Microsoft website said his employment at the company ended in early November.

After working at General Electric Co. for 17 years, Scott joined Microsoft in July 2005 as CIO and corporate vice-president. He headed information technology at the company and reported to chief operating officer Kevin Turner.

Microsoft said general manager Shahla Aly and corporate vice-president Alain Crozier are taking over Scott's duties until a replacement is hired.

Microsoft shares slipped 32 cents on Nasdaq, closing at $36.41 US.
