Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4480970 (released January 8, 2019) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

• Addresses an issue that may prevent some applications from displaying the Help (F1) window correctly.
• Addresses an issue in the Universal CRT that sometimes causes the AMD64-specific implementation of FMOD to return an incorrect result when given very large inputs. FMOD is frequently used to implement the modulo operator in JavaScript and Python implementations that use the Universal C runtime.
