On October 5th, this newest version will begin coming pre-loaded on new PCs and, much like Windows 10 was for Windows 7 and 8 PCs, it will be available as a free upgrade for Windows 10 PCs. You may not see this update on your PC immediately, since Microsoft usually chooses chunks of devices to roll these major feature and version updates out to in phases. It’s also possible that your IT department or provider may have blocked the update from applying—just to avoid any unexpected incompatibilities from an unforeseen auto-update!
