As a result, up to four toast notifications might appear simultaneously–three-high priority notifications and one normal priority notification.

  • Addresses an issue that causes SystemSettings.exe to stop working.

  • Addresses an issue that affects searchindexer.exe and prevents Microsoft Outlook’s offline search from returning recent emails.

  • Addresses an issue that increases the startup time for Windows. This issue occurs because a UI thread in a networking API stops responding when a 5G wireless wide area network (WWAN) device is slow to wake up.

How to get this update

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.
