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 This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.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

    When I installed the latest updates on my laptop, my Bluetooth wasn't turning on (installed all updates as of 3/20/2021).

    In the Device Settings, "Bluetooth is turned off" showed up without any switch to turn it back on.

    I fixed it by going to Control Panel > Device Manager and rolled back the Intel Bluetooth driver, so it does seem to be the newest Bluetooth driver that is causing the issue. 

    I have experienced the same problem in the past as well, and I hope Windows addresses these Bluetooth issues because these devices are becoming more and more essential every year.

    Hello. I was told to install Update 20H2 to maintain the right to security updates, as my previous version would reach its EOS (end of support) date. The problem is, Update 20H2 takes around 5 hours to install for small features such as a uncustomizable Dark Mode. Then when one tries to start their computer again the next day, the update suddenly no longer works and uninstalls itself via the Undoing Changes Made to your Computer notice. Initially, I thought the process would brick my computer into a loop and trust me, with the coronavirus around, you don't want to have to buy another computer. Luckily, it only took an half-an-hour. I do recommend that the end of life for version 1909 should be delayed while you fix these crucial errors and reduce the install time.

    -Sincerely,

    Customer Trevor Dylan Tavoularis

    Dude.... Windows 10 version 2004 and version 20H2 updates, make OS slower. Although the google chrome, games or some apps are not related Microsoft can run normally. But Everything related Microsoft application making slow.

    • Microsoft Word , Excel , OneNote and others making slow sync or failed sync, this is bad for my education.
    • The Search function in windows 10 is getting STUCK, this is unsatisfied that I can't make a shortcut through the search bar.
    • The Windows 10 Settings (Win + I) getting slower than last version.
    • Microsoft Store stuck loading, can't install any application.
    • Stuck in log in account screen.

    Please fix the Windows 10 20H2 updates, it is very serious issue on my education. Thank you, Microsoft.
