Microsoft has just rolled out a new Insider update for Office 2016 productivity suite on Windows desktop. The Office 2016 Build 10813.20004 for Windows desktop comes with new features for Word, Excel and PowerPoint. The update is currently only available for insiders, but it'll soon make its way to the users in the production ring as well.

One of the more desired features in this new version of the Office productivity suite is the ability to rename your Microsoft Word, Excel and PowerPoint files that are stored in One Drive or SharePoint. To access this feature you would need to click on the top-level app title bar to access this new Rename capability.
