The new OS hitting the markets is the Windows 7. It would just simplify the working on a PC big way as now there is less waiting, fewer clicks and less complexity for the users. There are hundreds of little improvements and a few big ones that add up to a whole lot of improvement in the OS.

All in all, Windows 7 is shaping up well. It can be considered as a far more modest release than Vista was, but it’s no worse for that. This new OS introduces compelling combination of welcome innovations and much needed polish, and that’s exactly what Microsoft needs right now. Vista’s foundation was solid and Windows 7 just made it better. Unlike its predecessor, Windows 7 is intended to be an incremental upgrade to the Windows line, with goal of being compatible with applications and hardware with which Vista is already compatible.

Presentations given by the company in 2008 have focussed on multi-touch support, a redesigned Windows shell with a new taskbar, a home networking system called Home Group and performance improvement.

Some applications that have been included with prior releases of Microsoft Windows including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery will not be included in Windows 7.

Bill Gates in an interview with News Week suggested that the next version of Windows would “be more user-centric.” Gates later said that Windows 7 will also focus on performance improvements.

Steven Sinofsky later expanded on this point explaining in the Engineering Windows 7 blog that the company was using a variety of new tracking tools to measure the performance of many areas of the Operating System on an ongoing basis to help locate inefficient code and to help prevent performance regressions.
