build 29531 1000

The tag build 29531 1000 refers to a specific Windows 11 Insider Preview build released to the Canary channel as part of a platform-development path. Microsoft offered Canary Insiders a choice between the existing 28000-series previews focused on 26H1 features and a new optional path starting with build 29531.1000, which begins the 29500-series flights. This build is described as a platform-development build, distinct from feature preview builds. The tag covers discussions about this optional update, its availability under Windows Update advanced options, and its role in Microsoft's Insider Program strategy for separating feature exploration from platform work.
