Improvements and fixes


This non-security update includes improvements and fixes that were a part of KB4041690 (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 are returned when the tolower() function is called.

  • Addressed issue where the Universal CRT _splitpath() function wasn't 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.

Symptom Workaround

The error message is, “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

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.
