Today, Microsoft released Windows 10 build 14372 for both PC and Mobile to the Fast ring. Coming just one day after 14371 for PCs, there wasn't much in the way of features.
In fact, there aren't any fixes or improvements listed either. Dona Sarkar, the head of the Windows Insider Program, said that 14372 has "a handful of fixes to improvement overall performance and reliability", but that's about it.
There were, however, a few known issues listed:
Clicking on networks or VPN connections in the network flyout on the taskbar doesn’t launch the network settings page like it should.
There are a few known issues with the Evernote Web Clipper extension for Microsoft Edge. The Evernote Web Clipper might not load on certain websites and there is no thumbnail image when clipping bookmarks. There are also various visual issues.
When you enable Developer Mode in this build, you will receive an error message because the necessary package needs from Windows Update isn’t being published appropriately. This will prevent you from using Device Portal. We’re working to get this fixed as soon as possible. You can still F5 deploy apps from Visual Studio to your PC.
If you're on the Fast ring, you can grab the update by heading to Settings -> Update & security -> Windows Update -> Check for updates. If you're not and you want to be, head to Windows Update but click on Advanced options. Under "Get Insider Preview builds", click Get Started. Once your PC reboots, go back to Advanced options and set the slider to the Fast ring. It will take about 24 hours before you see a build.
