Microsoft Crushes 300 Bugs With Second Windows 10 Insider Preview Build In Two Days

Microsoft is definitely committed to getting Windows 10 out the door on time. On Monday, the company released Windows 10 Insider Preview Build 10158, which brought a number of updates to the Edge browser and Cortana along with various UI updates. But Microsoft is definitely in a bug killing mood, which explains why just one day later it issued Build 10159 to the Fast ring.

While the build number has advanced by just one digit, there’s a lot going on under the hood according to Microsoft’s Gabe Aul. In fact, over 300 bugs have been exterminated with this Windows 10 Insider Preview 10159.

“Why two builds so fast back to back?! As you probably know, we validate builds that we produce in internal rings where they’re used by engineers in OSG and Microsoft,” said Aul. “If they pass all of our criteria we make them available to Windows Insiders, first to Fast and then to Slow once we know it’s a stable build.

“As it turns out though, 10159 is also a great build and passes our criteria for the Windows Insider Fast ring.”

It should also be noted that Build 10159 marks the first appearance of Microsoft’s new laser light wallpaper which we first talked about last week.

Since we’re heading through the home stretch, don’t expect to see any new features added to Windows 10 over the next few weeks. Leading up to the July 29 retail release of Windows 10, we should see a steady stream of builds that do nothing more than eradicate even more bugs and polish an already damn fine UI that Microsoft has developed to appease those that were less than thrilled with Windows 8.x.

Windows 10 is a free upgrade for Windows 7 and Windows 8.x users during the first year of availability. That means that if you don’t upgrade to Windows 10 by July 29, 2016, you’ll have to pay to upgrade just like everyone else running Windows XP or Windows Vista.
