Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4041681 (released October 10, 2017) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

• Addressed issue with the Universal CRT where _stat32i64() returns an incorrect drive number (error 0xFFFFFFFF) when using a relative path.
• Addressed issue in the Universal CRT where incorrect characters were returned when the tolower() function was called.
• Addressed issue where the Universal CRT _splitpath() function was not handling multibyte strings correctly, which caused apps to fail when accessing multibyte filenames.
• Addressed issue where the Universal CRT caused linker (link.exe) to stop working for large projects.
• Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

Workaround
Microsoft is working on a resolution and will provide an update in an upcoming release.[/TD]

Symptom
Installing this update may cause applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) to fail when creating or opening Microsoft Excel .xls files. The error message is, “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

Workaround
Download and install the Microsoft Access Database Engine 2010 Redistributable, and then modify the DB connection strings in Microsoft Excel to use ACE as a provider. Example: Change Provider=Microsoft.Jet.OLEDB.4.0 to Provider=Microsoft.ACE.OLEDB.12.0.
