Unfortunately, KB4049370 also brings issue of its own. Microsoft included four known bugs on the list:

  •  This update may change Czech and Arabic languages to English for Microsoft Edge as well as other apps.
  • KB4049370 may cause apps based on the Microsoft JET Database Engine, including Microsoft Access 2007 to crash when creating or opening Microsoft Excel .xls files. The error message that appears on the screen is the following: “Unexpected error from external database driver”.
  • UWP apps that use JavaScript and asm.js may stop working.
  • After installing the update and rebooting, the error message “Update needs a restart” may appear on the screen.

Microsoft is working on finding a fix for all these bugs and will provide an update in an upcoming release.
