To be completely honest about it, there's not much difference between this build and the previous one, so I'll just let MS do the talking for 16275:

• We fixed an issue resulting in Asphalt 8 not accepting input in recent flights.
• We fixed an issue from recent flights where when Slideshow was enabled resuming from sleep a second time might place the Lock screen in a state where it couldn’t be dismissed without pressing Ctrl + Alt + Del.
• We fixed an issue that caused minimized per-monitor DPI aware windows to miss DPI changes and end up with a mix of DPI scaling upon restoring.
• We fixed an issue in XAML resulting in text animations appearing slightly blurry in the last flight until the animation had stopped (for example, when loading the main page of Settings).
• We fixed an issue resulting in progress wheels on certain websites in Microsoft Edge unexpectedly moving out of place during their rotation.
• We fixed an issue resulting in an unexpected change in mouse sensitivity in the last flight for PCs using non-default display scaling.
• We fixed an issue resulting in the taskbar being unexpectedly thick if you booted up the PC while plugged in to an external monitor with a different DPI.

As ever, the full release note (there's nothing more for PC in there, trust me) are here.
