Microsoft has been very shy about pinpointing the Windows 7 release date in the past, but a recent presentation given at the company’s WinHEC conference pretty much confirmed the software giant plans to have the operating system ready Granted, the OS still needs some polishing here and there, but Windows 7 is a straightforward update from a technical standpoint since it is essentially built on the foundation of Vista but with some important enhancements centered on speed, usability and memory use. Here’s hoping the company can avoid past mistakes and have the operating system ready to roll in time for the holiday season 2009.
