Amy Hood, a key executive inside the Microsoft chain, has been appointed chief financial officer, the Redmond company announced on Wednesday. Following the departure of Peter Klein, who was with the company for almost 11 years, a huge hole was left in the Microsoft ranks; Klein will stay on through June to help Hood get acclimated.

"Amy brings the right talents and experiences to the role as we continue to strengthen our focus on devices and services," said Steve Ballmer.

Hood previously helped with key financial strategies after joining Microsoft in 2002. Her biggest achievement was executing the acquisition of Skype, which Microsoft purchased for $8.5 billion. In addition, Hood was a key part of Microsoft's Yammer acquisition. Hood's other experience includes chief of staff in the Server of Tools group, and many leadership roles within the Microsoft Business Devision.
