Microsoft has released an out of band cumulative update KB5004760 for Windows 10. The new update fixes an issue with PDF files not opening on the web when using Internet Explorer 11 or similar applications that are based on the 64-bit version of WebBrowser Control. Another issue related to PDFs that the update says it fixes is a rendering problem where the PDF file’s background would only be displayed in the color gray when using the Adobe Acrobat plug-in. The update also includes certain improvements to the servicing stack.
As usual, a few known issues are present in this cumulative update. They are listed below alongside their possible workarounds:
When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allows the input of Furigana characters, you might not get the correct Furigana characters. You might need to enter the Furigana characters manually.
Note: The affected apps are using the ImmGetCompositionString() function.

Note: Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps.
To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the using SSU:
