Just one day after its release, 14 million systems are now running Windows 10, according to Microsoft.

The staggered roll-out of Windows 10 to those who have "reserved" a copy will continue over several weeks, with Windows 7 and 8 users being notified of when their upgrade is available with an icon in their system tray. While we liked Windows 10 a lot, we wouldn't be too eager to upgrade just yet.

Over the last few days Microsoft has released a number of patches to fix Windows 10 bugs, and they're set to continue as the operating system is refined and adjusted. Giving Microsoft a few weeks to smooth a few of Windows 10's rougher edges will make for an easier life.
