Today, the Microsoft is rolling out Windows 10 Build 16188 to Insiders in the Fast Ring. But, this build isn’t as huge as the build from last week (16184).
In this build , Cortana finally has a dedicated settings page in the Settings app. Previously, users would need to configure Cortana’s settings from the settings page in Cortana itself — but now, all of Cortana’s settings can be configured from the Settings app which was a much-needed change. This simply makes it easier to configure Cortana as it no longer has its setting separated from all of the other settings in Windows 10. Another neat change in the Settings app: the Windows Insider Program’s section now has a Ninjacat icon!
Microsoft is also adding a bunch of improvements to the PDF viewer in Windows 10 with the release of build 16188.
