Microsoft has yet to officially confirm it is in the works, there have been several hints pointing to Windows 12 expected to arrive in fall 2024. One of these came at the Build 2023 developer conference in the form of a video screenshot that referred to a “next generation” of Windows. That presumably refers to Windows 12 and hopefully not a fully cloud-based Windows 11.
Microsoft has also referred to a “Next Valley Prototype Design,” said to be a codename for the next-generation of Windows. According to speculation, Microsoft intends to roll out Windows 12 in the third quarter of 2024, followed by a wider rollout in 2025.
Another report on Windows 12 suggests that it will be separated into “states” that live on different partitions of the storage drive. This will reportedly make managing and updating Windows 12 easier for Microsoft and a less daunting experience for users. It will also make the OS more secure and offer faster updates.
