14 million devices got Windows 10 in the first day after launch

Microsoft Windows 10 arrived on July 29 as expected, and the first 24 hours shown "unprecedented demand" for the new operating system, "with reviews and customer feedback overwhelmingly positive around the globe."

The free Windows 10 upgrade for existing Windows 7 and Windows 8 users that qualify is rolling out in phases, about the same way as the OTA updates for Google Android. The Windows Blog post about the first day after launch reveals that "we now have more than 14 million devices running Windows 10." The same source also points out that "we still have many more upgrades to go before we catch up to each of you that reserved your upgrade." 

For those who face any kind of problems while upgrading to Windows 10, multiple support options are available: one-on-one technical support from Microsoft; technical support from retailers such as Best Buy, Wal-Mart, Staples, and many more; Answer Desk services in Microsoft Stores.

Realtime web monitoring service Akamai reported a 35 percent increase in global Web traffic on July 29. This is not something unexpected since the size of a single Windows 10 upgrade package is 3.5 GB. It is too early to say if Microsoft will succeed in having Windows 10 running on a billion devices in a few years as planned, but the start surely looks strong.
