Microsoft Windows 10 'Sets' won't be in Redstone 5
Confirmed by Microsoft.
Thank you for your continued support of testing Sets. We continue to receive valuable feedback from you as we develop this feature helping to ensure we deliver the best possible experience once it's ready for release.
Starting with this build, we're taking Sets offline to continue making it great. Based on your feedback, some of the things we're focusing on include improvements to the visual design and continuing to better integrate Office and Microsoft Edge into Sets to enhance workflow.
If you have been testing Sets, you will no longer see it as of today's build, however, Sets will return in a future WIP flight. Thanks again for your feedback.
