In a presentation on Thursday, Microsoft COO Kevin Turner said the company had successfully shipped 60 million copies of Vista, its latest OS offering, since its January 30 release. These numbers showed the OS was well close to beating pre-release expectations.

Turner made this disclosure during the annual meeting of financial analysts at the company’s headquarters in Redmond. He said the company was looking to ship a billion copies to retailers, consumers, and PC manufacturers at the end of the next 12 months.

Vista has created ripples in the market since its entry. Turner said in the first five weeks in the market, it had already surpassed the total number of Apple installations. Earlier information handed out by Microsoft had claimed shipment of 20 million Vista copies in the first month and 40 million in the first 100 days
