Analysis: Windows Copilot on the Horizon
The timing of this announcement aligns with the logic of introducing the update ahead of a broader rollout that will follow shortly. Windows Latest speculates that the 23H2 update may become available next month, albeit in a limited form. This implies that users who have opted to receive updates as soon as possible could start receiving the update in October, with the usual phased deployment process. The wider rollout is projected to commence in November, encompassing all users and delivering the new features bundled with the upgrade.
