With Windows 10's July 29 launch just a few weeks away, Microsoft is offering up more details on how it'll celebrate the birth of its new baby. And one thing is clear: This is a far bigger deal than when Windows 8 hit the streets. Along with the usual festivities and a new marketing campaign, Microsoft is also promoting the idea of "upgrading the world" by offering consumers a bit of help with moving towards Windows 10, as well as celebrating inspirational non-profits all over the world. Microsoft stores, as well as retailers like Best Buy, Walmart and Staples, will offer in-store upgrade help and "experience stations" to let you try out Windows 10. The educational push makes sense, since Microsoft is making Windows 10 available for free to existing Windows 7 and 8 users for its first year. This time around getting people to upgrade means a lot more to Microsoft than making them pay retail price for a new OS.
