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 This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.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.

    Haven't forgotten about you Louie.  Life happens!  Thanks for the screenshots.  I sure was hoping someone with

    more knowledge than myself could have helped you by now 🤔.  As I've mentioned before, I'm no computer

    expert and am learning myself as things go along.  

    I'm hesitant to give you wrong/harmful information/advice.  That being said:

    On the troubleshooting screenshot you posted, at the bottom where it says "View detailed information" --

    did you click on that and see if it gave any further information?    How old is your laptop/desktop?  Make/Model????  

    By chance, have you tried logging in as Administrator when trying to get updates?  Do you run any 3rd party

    anti-virus software, VPN's, Malwarebytes, Ccleaner programs? - anything like that? - 

    Sometimes those programs CAN interfere with an update.  

    Before I tell you about how I did the update there are several IMPORTANT things to do before running the program,

    and I do not have the time tonight to explain. I will try tomorrow.  In the meantime I'm curious for answers

    to the above questions I asked about.

    If you haven't already, I would take the TIME needed for you to back up important files from your computer. 

    Too many users have lost precious photos, files, years of work, etc.    Personally, I back up to

    an external hard drive, flash drives, DVDs, a few things I store in a cloud service.  Whatever it takes to save

    what you don't want to lose.  If you haven't, it's a good and necessary project for you to do before updating to 20H2....  

    it's good practice anytime actually!  Computers crash and your stuff is GONZO.  Where is mrdbeta when I need him? 😄

    In regard to your questions:

    You can web search the features in Windows 10 20H2 if you're so inclined.  Not sure what you mean by resetting

    your pc.  As far as setbacks...  uhhhh, depends upon whom you ask.  Those who have many problems will say YES

    others will say NO and others SO-SO!! It's a ****-shoot.  I'll wait to see your answers to above.
