Microsoft has released a new Windows 11 build 22572.100 (KB5012817) to the Dev Channel insiders. The new build does not bring anything new to the table as it is a cumulative update with which the company is testing its servicing pipelines as it is often known to do.
The official announcement says:
We are starting to roll out Cumulative Update Build 22572.100 (KB5012817). This update does not include anything new and is designed to test our servicing pipeline for builds in the Dev Channel.
Hence, all the bug fixes and improvements that were announced with the earlier released build 22572 to the Dev Channel are carried over into this. The build has loads of new features as we are now moving into the next phase of Windows 11 in preparation for version 22H2.
Interestingly, while there are no new changes made in this build, servicing test builds like these before have been known to break some features. For example, Windows 10 Build 21292.1010 caused issues for x64 emulation on ARM PCs.
