Neowin reports that a day after Microsoft rolled out its latest Windows 10 Insider Preview, build 10166, the newer build 10176 has leaked online, just days before the OS is expected to reach the RTM milestone.

Since this leak is still very fresh, we don't yet know what improvements or features it brings compared with other recent builds. However, Microsoft has made it clear that remaining builds leading up to Windows 10's launch on July 29 will focus on bug-fixing and adding polish to the user experience, so don't expect to see any big new features in there.

As ever, we recommend caution if you choose to download and install this build. Given that it's a leak and not an official release, there may well be significant issues that aren't well-documented by Microsoft, so if you're not equipped to deal with unexpected bugs, you should think twice before installing it.
