The Windows 10 April Update is here, bringing with it new features like Timeline, security and accessibility improvements, and some visual tweaks from Microsoft's new "Fluent Design." So how do you get it? 

There are a few ways to install the latest Windows update right now. One: type "check for updates" into Search to pull up the Windows Update settings menu, where it may already be available. But Microsoft gradually rolls the automatic update out to the millions of computers running Windows, so there's a good chance it's not there for you yet. Thankfully, it's easy to update manually, too.
