Windows 10 KB5000842 (Build 19042.906) Full Changelog

With this update, Microsoft is finally fixing the “Computing Filters” message when using filters in File Explorer search results. Another bug has been fixed where the search filter freezes or stops responding when users try to change the type of filter used (file type, file date, for example).

KB4601382 update

Microsoft has also fixed performance issues caused by explorer.exe, which is responsible for File Explorer, Taskbar, Action Center, and other important elements.

As we reported recently, a bug in Windows 10 causes explorer.exe to consume high amounts of memory, particularly when other apps are running in the background, which obviously affects the system performance.

This has been addressed with today’s update.

In addition to File Explorer fixes, Microsoft has also patched an issue where some monitors will produce colours darker than expected. This is experienced only when you’re using HDR mode, a feature available for select monitors only.

Another bug has been fixed where video playback sync doesn’t work when you use multiple monitors.

This cumulative update will address an issue where the system will stop responding to mouse or keyboard inputs when users delete files/folders synced to OneDrive.

Windows 10 Build 19042.906 is also expected to address problems:

  • Unexpected issues when using the touch keyboard and changing device orientation
  • A bug where users cannot dismissing the toast Notifications using the Close button.

Like every other optional update, you should avoid it unless you’ve been having the problems highlighted above. You can always wait until the next Patch Tuesday to apply both security and these non-security fixes.

The next Patch Tuesday is currently scheduled for April 13, 2021.
