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 This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.

Note Devices 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 youâre updating to. You will then need to update to the later version of Windows 10 after the issue is resolved in your environment. Note Within 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 before the default uninstall window has lapsed. For more information, see DISM operating system uninstall command-line options.

We are working on a resolution and will provide updated bundles and refreshed media in the coming weeks.
How to get this update

Cumulative Update KB4517245 Windows 10 v1909 Build 18363.329 - Sept. 5 Insider

JennyWilliams_642 · Mar 9, 2021

windows 10 updates-March 2018

I have March updates that will not install. The automatic updates for 2018-03 Cumulative Update for Windows 10 version 1709 for x64 based system (March KB4088776) were activated and downloaded to my computer, but they will not install on shutdown/restart.
When I check for updates, it shows that the updates are downloaded, but when I click to uninstall, there is not a date for installation. I have researched the Windows suggestions for this problem. They tell me to remove the January 2018 updates (January
KB4056892) and then reinstall the March update. When I attempted to uninstall the January update, I could see the update listed in the check for downloads screen, but when I click uninstall, the January update has a different reference number. Please advise.
I have talked to my technology department and they can't determine next steps either. VERY FRUSTRATING. I need my computer for work.
