Windows 10 build 14352, a preview version of the upcoming Anniversary Update (also known as Redstone), comes with an eagerly awaited change that Microsoft hasn’t yet announced publicly.
The 260-character path length limit in Windows can be removed with the help of a new policy, thus allowing you to run operations with files regardless of their path or file name. While this new rule is not enabled by default, admins can turn it on by following these instructions.
The Windows Game Bar is one of the more overlooked features of Windows 10. You can now say "Hey Cortana, set a timer for 10 minutes" and the assistant will oblige, whether your PC is unlocked or not.
Windows Ink gets a lot of updates in this build. Sticky Notes have been updated to use Inking.
Limited Periodic Scanning is a new feature that restricts scanning to longer interval schedules. Windows Ink Workspace has also seen some notable improvements.
Finally, Microsoft updated the Feedback Hub with a bit more, well, feedback. The Unified Windows Platform is a program with which Microsoft will bridge the gap between the Xbox One and Windows platforms, and UWP will allow developers to create games and applications that will work on devices that run on both platforms.
It can also open recent files so if you're on another computer that doesn't have the file or Office installed, you will still be able to open it and edit it within your browser.
Microsoft added a compass to Windows Ink's Sketchpad, presumably to let you know if your drawings were literally on the level.
