Microsoft Edge, initially developed under the codename Project Spartan, is a web browser in development by Microsoft. The company has integrated several user suggestions to the browser, including a home button, a more customizable New Tab page, password auto-fill, as well as the ability to import favorites/bookmarks from other browsers and to play music from a minimized tab.

"Our last build to the Windows Insider Fast ring was just yesterday, but we’re following it up with another build today – Build 10159, releasing to the Fast ring," Microsoft said in a blog.

"We’d been using 10158 for almost a week and knew it was going to be a strong build, and the data backed that up so we released it yesterday. Hot on its heels though was build 10159, which in addition to more fixes (over 300 of them!), took in one very interesting change. We didn’t want to wait with 10158 so we went ahead and released that build while we were still evaluating 10159. As it turns out though, 10159 is also a great build and passes our criteria for the Windows Insider Fast ring," the blog read.

Also, Cortana, an intelligent personal assistant developed by Microsoft, can now issue flight or work alerts and it can help the users send emails without typing anything. The users simply have to speak the recipient's email address, the missive's subject line and contents in that order.

In addition, Windows Photos app now also supports GIFs and has an 'Open with...' option. Also, Skype Wi -Fi has been completely replaced with Microsoft Wi-Fi, which the users can use to buy access to hotspots in chunks of time using Windows Store's payment methods.

Microsoft will officially launch Windows 10 on July 29.
