Barely a day after Microsoft launched the previous Windows 10 Insider Preview build, the company has released a new build that primarily addresses a range of bugs and other issues in the operating system.

Microsoft has fixed over 300 bugs in the Windows 10 Insider Preview build 10159, which is pretty impressive considering build 10158 was released just yesterday. The company is clearly working hard to ensure Windows 10 is ready for its release in just under a month's time, and bug fixes are a big part of this process.

Build 10159 also brings with it the new default wallpaper that Microsoft announced a few days ago. The login screen has been updated as well to reflect how it will look come the public launch of the OS.

This new build of the Windows 10 Preview is now available for those in Microsoft's Insider program who are on the Fast Ring. If you were already downloading build 10158 when this new build was released, you may run it to an error, which can be resolved by simply restarting your PC.
