Last night, Microsoft released Windows 10 for PCs build 14393.10 to the Fast, Slow, and Release Preview rings. At the time, it was an Insider Preview cumulative update, but now that the Anniversary Update is released, it"s just a regular old Windows 10 update.
There was a bit of accidental misinformation when the update was initially released. Dona Sarkar first tweeted that it was available to the Fast ring only. She also promised a changelog "soon" in the Feedback Hub. That particular changelog still hasn"t appeared, but there is now one on the Windows 10 Update History page.
Here"s what got fixed in Windows 10 for PCs build 14393.10:
Improved reliability of background tasks and extensions for Microsoft Edge.
Addressed licensing issue that prevents apps from activating.
Addressed issue that prevents changing display orientation after attaching a keyboard dock.
Addressed issue with scheduled update scans that are delayed during Connected Standby.
Addressed issue that sometimes prevent Extensible Application Markup Language (XAML) apps from receiving keyboard input.
Addressed issue with event logging that creates very large virtual allocations.
Addressed issues that cause high battery drain when a Windows 10 Mobile device is idle or the screen is off.
Addressed additional issues with Cortana, Microsoft Query and Microsoft Excel compatibility, and the Korean Input Method Editor (IME).
