The earlier Windows 10 shift to allow overlapping Windows Store Apps, the return of a Start Menu with rich information, and integrating Cortana speech and search technology were all welcome changes from Windows 8. However, after using Build 10122 for a few days, it is now unclear to me what Windows 10 will deliver to what Microsoft hopes will be one billion eventual customers.
