    Windows Update Improvements
    Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

    Known issues in this update

    Symptom Workaround
    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.
    We are working on a resolution and will provide an update in an upcoming release.
    Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.

    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:

    1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu /f:Windows10.0-KB5000842-x64.cab <destination path>
    2. Extract the SSU from the previously extracted cab via this command line: expand Windows10.0-KB5000842-x64.cab /f:* <destination path>
    3. You will then have the SSU cab, in this example named SSU-19041.903-x64.cab. Slipstream this file into your offline image first, then the LCU.

    If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the new Microsoft Edge. If you need to broadly deploy the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business.

    How to get this update

    Before installing this update

    Microsoft now combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

    Prerequisite:

    For Windows Server Update Services (WSUS) deployment:

    • Install the May 11, 2021 update (KB5003173) before you install the latest cumulative update.

    For offline Deployment Image Servicing and Management (DISM.exe) deployment:

    • If an image does not have the February 24, 2021 (KB4601382) or later cumulative update, install the January 12, 2021 SSU (KB4598481) and the May 11, 2021 update (KB5003173).

    Install this update

    Release Channel Available Next Step
    Windows Update and Microsoft Update Yes None. This update will be downloaded and installed automatically from Windows Update.
    Windows Update for Business Yes None. This update will be downloaded and installed automatically from Windows Update in accordance with configured policies.
    Microsoft Update Catalog Yes To get the standalone package for this update, go to the Microsoft Update Catalog website.
    Windows Server Update Services (WSUS) Yes This update will automatically sync with WSUS if you configure Products and Classifications as follows:
    Product: Windows 10, version 1903 and later
    Classification: Security Updates

    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.

    Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.

    For a list of the files that are provided in the servicing stack update, download the file information for the SSU - version 19041.1081, 19042.1081, and 19043.1081.

    All went in fine. But I noticed in settings, the account picture and other info has gone. I cannot remember exactly what was in there as it is now gone. Anyone else seeing the same? Guess it's been intentionally removed by MS
