Microsoft is beginning to roll out the second June cumulative update for Windows 10 version 1903 that includes numerous fixes, including one for the Windows Event View custom views crash. This update was released to Windows Insiders earlier this week to test before being made publicly available today.

The update is titled "2019-06 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4501375)" and does not contain any security fixes.

While there are numerous issues resolved with this update, one that stands out is a fix for Custom Views crashing Event Viewer.

Additionally, the application may stop responding or close. You may also receive the same error when using Filter Current Log in the Action menu with built-in views or logs.

This build also fixes an issue with Night Light not working after a shut down.
