Microsoft released two new builds today, Windows 10 Insider Preview build 14366 for PCs and Windows 10 Mobile Insider Preview build 14364 for smartphones. Both builds are aimed primarily at preparing for this summer's massive Anniversary Update, along with kicking off June's Bug Bash frenzy.
Nevertheless, there are two small additions in this build, and here they are:
Office Online for Microsoft Edge: Use Word, Excel, PowerPoint, OneNote and Sway Online without needing Office installed. The Office Online extension is the quickest way to view, edit, create Office files in Microsoft Edge! You can also quickly access your recent files, thanks to integration with OneDrive and OneDrive for Business. Visit our extensions page at the Microsoft Edge Dev website to learn more and try it out for yourself!
Windows Store Update: A Store update (Version 11606.1000.43.0) is rolling out today that includes some good performance improvements to prevent the Store from crashing and using up too much resources on your devices. You should see an overall improvement navigating the Store and visiting app pages.
So, download and install the updates to help get Windows 10 ready for its Anniversary Updates. But be sure to keep these new items in mind while you're at it.
