Windows 10 Reaches 14 Million Installs

Microsoft's new operating system, Windows 10, launched on Wednesday and is currently rolling out in phases. It now appears the first phase was a big one, as Microsoft says on its official blog that Windows 10 has now been installed on 14 million devices. Many more upgrades are still to come.

"We still have many more upgrades to go before we catch up to each of you that reserved your upgrade," Microsoft marketing boss Yusuf Mehdi said.

"Rest assured we are working 24×7 to continue the upgrade process and are prioritizing the quality of your upgrade experience over anything else," he added. "We are grateful for your excitement and enthusiasm and we appreciate your patience over the days and weeks ahead as we carefully roll out Windows 10 in phases to all of you that have reserved."

People who reserved a Windows 10 upgrade will be notified through the system tray (see image) when their upgrade is ready. If you didn't reserve an upgrade already, you can do that here.

Mehdi said demand for Windows 10 has been off the charts.

"We're humbled and grateful to see the response to Windows 10," he said. "We have seen unprecedented demand for Windows 10, with reviews and customer feedback overwhelmingly positive around the globe. We are doing everything we can to upgrade the world to Windows 10 as quickly as possible over the coming days and weeks ahead."

Overall, Microsoft hopes Windows 10 can reach 1 billion devices by 2018. As part of a special offer,Windows 7 and 8 users can upgrade to Windows 10 for free for the first year after launch.
