General changes and Improvements
- KB4519978 addresses a bug that causes printing from 32-bit applications to fail on the following error – “Access is denied”. This appears when you select Run as a different user for the concerned application.
- Resolves an anomaly that sometimes causes the Resilient File System (ReFS) to stop working.
- Improves the compatibility status of the Windows ecosystem so as to make different apps compatible with upcoming updates to Windows.
- Build 17134.1099 addresses an issue with a race condition between the volume mount process (within fileinfo.sys) and the deregistration of filter notifications that cause the operating system to stop working on certain virtual machines. The error code is “0x7E.”
- Resolves the underlying cause that results in your device entering into Windows out of Box Experience i.e. OOBE. If your system ever enters in such situations, it will stick into a restart loop.
- Updates the time zone information of countries like- Australia, Fiji Islands, and Norfolk Island.
- KB4519978 works upon an issue that may restrict that scroll bar from being selected when an ActiveX control implements the CScrollView class. This bug appears if you move the Internet Explorer window, which then moves the scroll bar to the left.
