Microsoft is releasing a new Redstone 5 build, build 17643, to Windows Insiders in Skip Ahead. The new build of Redstone 5 includes some more improvements to Windows 10’s upcoming Sets feature which introduces a tabbed experience for apps.
Sets in build 17643 now works with Office apps like Word, PowerPoint, and Excel. Those part of the Office Insiders program can now use Sets with Office apps as long as they are running the latest updates for the apps.
Once you are on the latest versions of these apps and running the latest Redstone 5 build, you will be able to use Office apps in a tabbed experience and switch between different documents, presentations, and spreadsheets easily. Sets in the latest build now also works with most Win32 apps using the default Windows titlebar, according to Microsoft.
Build 17643 includes a couple of other improvements — Microsoft Edge’s WebDriver is now an on-demand feature, Data Roaming now shows your data usage and more. You can find the full changelog here.
