Today Microsoft is kicking off an exciting week at our Worldwide Partner Conference in Toronto. Windows Server 2012 will be a focus of attention at the event, of course, and it is nearing final release. In fact, at the conference we are announcing that Windows Server 2012 will be released to manufacturing in the first week of August. The code will be complete and we will begin delivering it to our hardware partners. Then, the product will be generally available to customers worldwide through multiple channels in September.
