Microsoft announced over 14 million users have upgraded their system to Windows 10 on the new operating system's launch day. Adoption is picking up much faster than Windows 8, which saw just 4 million installs over the weekend after its release. Details about how many Windows users reserved a place in the Windows 10 update queue weren't revealed.
As we’ve shared, our top priority has been ensuring that everyone has a great upgrade experience, so, we are carefully rolling out Windows 10 in phases, delivering Windows 10 first to our Windows Insiders. While we now have more than 14 million devices running Windows 10, we still have many more upgrades to go before we catch up to each of you that reserved your upgrade. Rest assured we are working 24×7 to continue the upgrade process and are prioritizing the quality of your upgrade experience over anything else. 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.
If you reserved your upgrade of Windows 10, we will notify you once your PC is ready for Windows 10 and it has been downloaded on your PC. The best way to know your upgrade is ready is to look for [the] notification in your system tray.
