Known issues

You might not see the correct Furigana characters when using the Microsoft Japanese IME to enter Kanji characters in an app so you need to enter manually.

Important – The affected apps are using the ImmGetCompositionString() function.

You will receive a resolution in an upcoming update
In case you have installed using Windows installation created from custom ISO image or offline media might remove Microsoft Edge Legacy removed but unfortunately, it doesn’t replace with the Chromium version. This occurs when the images are created by slipstreaming this update into the image without having first installed the standalone SSU rolled out earliest 29/03/2021.

Important – If you directly receive updates then the error will no longer occur. This contains devices carrying Windows Update for Business. You should directly receive updates or SSU without any extra steps.

In order to prevent, slipstream the Servicing Stack Update rolled out  29/03/2021 or later into the ISO image or custom offline media before doing the same with the Cumulative Update. Therefore, with the LCU wrapped up with SSU used for Windows 10 20H2 and 2004, you will have to extract the SSU from the combined package. Follow the instructions –

Unpack the cab from the msu following cmd command ( for instance KB5003173): “expand Windows10.0-KB5003173-x64.msu /f:Windows10.0-KB5003173-x64.cab <destination path>” (without quotes)

2. Unpack the SSU from the earlier extracted cab through – expand Windows10.0-KB5003173-x64.cab /f:* <destination path>

3.Now you have already got the SSU cab, in this example, SSU-19041.985-x64.cab. Slipstream this file into your offline image, then the Latest cumulative update.

Alternatively, you can install Microsoft Edge from here or Microsoft Edge for business from here.
