Zac Bowden

Windows 10 build 10558 has leaked onto the internet today, featuring improvements to Microsoft Edge and a new Messaging app which Microsoft announced back in January. The universal messaging app will allow people to communicate with friends over Skype, and eventually via SMS.
As per all leaks, we will not be linking directly to the download. We also ask you to not post links in the comments section. The leak comes from WZOR, so a little creative searching should do the job. As per all leaks, we also don’t recommend you use this build on your primary hardware.
Microsoft is currently preparing for its October 6th event next week (bookmark our dedicated #Windows10devices event page), in which the company is expected to unveil a wide array of new devices and showcase new improvements coming in Threshold 2. Build 10558 includes a few of those new features Microsoft is planning to demonstrate.
