Microsoft releases Windows 10 Redstone 5 Build 17618 for Skip Ahead -- and it includes Sets!

While Microsoft is busy putting the finishing touches to the Windows 10 Spring Update, codenamed Redstone 4, work is well underway on its successor, due around October time.

Windows Insiders who opted to "skip ahead" can try out early Redstone 5 builds, and today Microsoft releases Build 17618 on that branch. Usually at this stage in development there’s nothing much to get excited about, but that’s not the case here.


Build 17618 includes Sets, a tab-based feature that’s designed to let you access related web pages, research documents, files, and applications in one location. Sets was originally planned to be part of  the Spring Update alongside Timeline, but Microsoft needed a little more time to get things right, and so pushed it back.

The feature, which made a brief appearance in Redstone 4 builds, is now available to test once more and there have been a number of improvements made to it. These include:

There are some keyboard shortcuts to try with it as well:

Sets can be enabled or disabled by going to Settings > System > Multitasking.

The Mixed Reality issues which blighted RS4 Build 17112 (notably crashes and an uncomfortably low frame rate) are present in this build, so if you are a Mixed Reality user you might want to skip this one.

Changes, improvements, and fixes in this build include:

Known issues include:
