Many Windows 10 users recently reported that the October “Tuesday Patch” prevented them from updating Office software. Second, in a support document, Microsoft acknowledges that Windows 10 can lose certificates when users use ISO or other media installation tools to update the system. There have also been reports that the October patch may have caused the file browser to crash or the blue screen to crash.

Although Microsoft has not confirmed reports of system crashes, there appears to be another impact on Office 365’s ability to get updates on some systems.
Windows Latest noted that after deploying the October 2020 patch, some users experienced an error message when they tried to update the Office Productivity Suite — “Downloading office 365 files failed, error s”.
Microsoft engineer David James has warned Windows 10 users on Twitter that the October update could prevent Configuration Manager and Memcm from downloading Office 365 update files.
In addition, after the Windows 10 2020 October patch is deployed, both the system and search capabilities may experience problems. As the root cause has not yet been found, it is recommended that you suspend this update.
If you really need to install office product updates, do so before you deploy the Windows 10 October patch (or uninstall the patch, install the Office update, and then hit the Windows 10 October patch).
Finally, Microsoft recommends that users avoid updating the Windows 10 operating system with a USB drive, DVD disc, or ISO image as much as possible, as these are intended primarily for devices that use management tools such as WSUS.
As for other issues introduced in the Windows 10 2020 October patch (blue screen, black screen, poor performance, audio failure, etc.), there is only a patient wait for the Microsoft Windows team to troubleshoot and fix them one by one.
