Known issues with KB5000802 and KB5000808

Symptom Workaround
System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be impacted if they have already installed any Latest cumulative update (LCU) released September 16, 2020 or later and then proceed to update to a later version of Windows 10 from media or an installation source which does not have an LCU released October 13, 2020 or later integrated. This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated. <br> <br>NoteDevices using Windows Update for Business or that connect directly to Windows Update are not impacted. Any device connecting to Windows Update should always receive the latest versions of the feature update, including the latest LCU, without any extra steps. If you have already encountered this issue on your device, you can mitigate it within the uninstall window by going back to your previous version of Windows using the instructions here. The uninstall window might be 10 or 30 days depending on the configuration of your environment and the version you’re updating to. You will then need to update to the later version of Windows 10 after the issue is resolved in your environment. NoteWithin the uninstall window, you can increase the number of days you have to go back to your previous version of Windows 10 by using the DISM command /Set-OSUninstallWindow. You must make this change beforethe default uninstall window has lapsed. For more information, see DISM operating system uninstall command-line options. <br> <br>We are working on a resolution and will provide updated bundles and refreshed media in the coming weeks.
(KB5000802 only) 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. <br> <br>NoteThe affected apps are using the ImmGetCompositionString() function. We are working on a resolution and will provide an update in an upcoming release.
After installing this update, you might receive an APC_INDEX_MISMATCH error with a blue screen when attempting to print to certain printers in some apps. Issue resolved with an out-of-band update.
After installing updates released March 9, 2021 or March 15, 2021, you might get unexpected results when printing from some apps. Issues might include:<br><ul style="margin-right: 0; margin-left: 0; color: rgba(54, 54, 54, 1)"><li style="margin-left: 0"><p style="color: rgba(30, 30, 30, 1)">Elements of the document might print as solid black/color boxes or might be missing, including barcodes, QR codes, and graphics elements, such as logos.</p></li><li style="margin-left: 0"><p style="color: rgba(30, 30, 30, 1)">Table lines might be missing. Other alignment or formatting issues might also be present.</p></li><li style="margin-left: 0"><p style="color: rgba(30, 30, 30, 1)">Printing from some apps or to some printers might result in a blank page or label.</p></li></ul> Resolved - Install KB5001649 from the links below.

    Hello,

    I just installed all of the updates and now my keyboard is not working . I am having to use the ease of access keyboard to type . Should I reset my system to yesterday, before the updates?

    Thank you for your assistance with this.

    I'm no expert by any means. However, since you've received all the updates, resetting to a previous state seems a bit excessive for now until you've searched 

    on line for answers.  Are you on a desktop/laptop? Make/Model?   Did you try running the windows keyboard troubleshooter? -and-  Check for new drivers

     for your keyboard?  There are many sites addressing this problem.  I'll give ONE just as example.  I'm sure someone with more knowledge will come along and be able to help you more than I can.  Seems to me if you revert back you may run into the same problem once you update again without first fixing the issue with your keyboard.  Hope you find answer easily!

    I have this issue:

    System and user certificates might be lost when updating a device from Windows 10

    After restarting the pc to see if it would fix it it now has been stuck on a blue screen that says restarting for the last 40 minutes. How do I roll back to my work in pc with all my programs and my photos and all my work , that disappeared upon installing this horrible update?? Thanks

    The update is asking me to install it yet a "Virtual box" app is preventing me from doing so. I already did Troubleshoot and did extensive lookaround on my PC and registry, and there is no "Virtual box" found.

    In addition, it messed up my sound settings and driver. The Windows notice mentioned that I would need to update to this new version or else I won't receive any more updates, yet this issue of a non-existest app is preventing me from just doing a simple upgrade.

    Hi Alex,

    Likely you have any other emulation software. To fix that, see 

    [FIX] Uninstall Virtualbox to update Windows 10 - Your Windows Guide

    Re Audio driver, I am sure it must be Conexant. Remove the Audio drivers and try to update again. Download the newest version of the Audio driver from the OEM.
