We have previously reported that Microsoft is stepping up development of a new generation of Windows operating system, the system is very likely Officially released this summer. Now, more details about this operating system called Windows Blue have been leaked.
Mary Jo Foley reports that the development of this operating system has been completed in half.
Windows Blue can be seen as an upgrade to Windows 8, and the new system may be available for free download for Windows 8 users. Microsoft is testing the system, and Microsoft will publicly release an MP preview before its official launch.
It seems that Windows Blue is just an upgrade to Windows 8, not a standalone new operating system.
One of the main changes in Windows Blue is the improvement to the "Search Bar" Microsoft has been improving this feature, and in Windows Blue, it will help users easily search for a variety of content, such as applications and movies.
In addition, Windows Blue will also be equipped with the latest IE 11 browser, which runs faster and better adapts to devices with 7-8 inch screens.
We believe that Windows Blue may not be the best new system name, because Blue (blue) does not seem to be Microsoft's lucky color. “Blue Screen of Death (BSOD)” has been a nightmare for Windows users.
