Following industry speculation that the DoJ ruling would lead to a haemorrhage of Microsoft staff, Tod Nielson, one of the company's key developer relations managers, has left the company just days after the ruling to split the software giant in two.
Nielson was responsible for the close links Microsoft forged with the software developer community. For 11-years, Nielsen had been involved in the development of a number of tools designed to make it easier for software developers to create Windows applications.
Nielsen's move follows the departure of a number of high-level executives, including former chief financial officer Greg Maffei.
The news will come as a blow to Microsoft which is planning to unveil its Next Generation Windows (NGW) strategy on 22 June. NGW is aimed at providing an infrastructure on which software developers can build Internet applications for Windows.
