Microsoft released one of its biggest Insider Builds for Windows 10 Monday. The latest version 15002 includes a ton of new features such as the Start menu in the Edge browser, Windows Ink, Cortana, Defender and other built-in features.

Lower Blue Light From Your PC At Night

Windows now lets you lower the amount of blue light coming from your PC at night. Go to Settings to turn this new function on or off. If you’re familiar with f.lux, then this won’t be a new feature for you, but most Windows 10 users are unaware of these additional tools. Research has shown that Blue Light can suppress the secretion of melatonin, which blue light at night does way more powerfully, according to this study from Harvard.

The Blue screen is turning green in the Insider builds. Microsoft says it made this change “in an effort to more easily distinguish Windows Insider reports vs the reports of those on production builds.”

Manage All Your Tabs

It can be pretty challenging to keep all of your tabs organized, and figure out where you left off. Microsoft added two new buttons next to your tabs in Microsoft Edge to help you manage all your tabs without losing your spot.

You can also launch a new window or new InPrivate window for Microsoft Edge by using the Taskbar icon. All you need to do is right-click or swipe up on the Microsoft Edge icon in the Taskbar, and pick the task you need.

Tile Folders In Start

From the Start menu, Windows 10 is getting support for folders to help you organize all your tiles. To get started, simply drag and drop a tile on top of another tile in Start to create a brand new folder.

This is just a small list of the new features in this build You can find the list of new features in Microsoft’s announcement here.
