Windows 10's July 29 "launch" next week is not a typical one for Microsoft. It's just the start of a slow and staggered rollout for the company's newest operating system.
Next week marks the start of availability of Windows 10 for PCs and tablets. Later in calendar 2015, as Microsoft officials said earlier this year, Microsoft will deliver Windows 10 Mobile for ARM- and Intel-based Windows Phones and new small ARM- and Intel-based tablets. Windows 10-based Surface Hub conferencing systems, HoloLens glasses and various IoT devices will happen starting later this year and beyond.
On Microsoft's earnings call earlier this week, Microsoft CEO Satya Nadella provided a rough timeline as to what Microsoft watchers should expect over the next few months, in response to a Wall Street analyst's question about the trajectory.
Nadella said the initial Windows 10 rollout would happen in three phases. The initial upgrade phase starting July 29, which is focused on getting Windows 7 and 8 users to upgrade, plus "retail execution." Then "come the fall you will see the devices from all the OEMs going into the holiday quarter," Nadella said.
Nadella also noted that "we have a release of enterprise features ... which will ship in that (fall) timeframe and I expect piloting to start and deployments to start in the second half of the fiscal year."
