Microsoft has been trying to push Copilot to as many users as possible, and to that effect, they have accelerated the seeding process to get the feature out to more and more users. The reasoning behind this is broad. More users means more feedback, and more data points to train their Copilot model. Initially, they restricted Copilot to Windows 11 as it is the newest version, but now, it looks like they want to expand Copilot usage to Windows 10 as well.
