Microsoft releases Windows 10 build 21359 to the Dev channel Apr 14, 2021 13:18 EDT with 1 comment Right on schedule, Microsoft today released Windows 10 Insider Preview build 21359. You might recall that last week, the firm switched over to the co_release branch, so unsurprisingly, there isn't much in the way of new features in this build. There are some minor things though. For one thing, there's a new option to restart apps after signing in, which will appear in the Power menu. Also, you can't upload new activity to Timeline anymore, so you'll need to use OneDrive or Office to view recent files; indeed, Microsoft seems to be killing off Timeline.
