Our Windows 10 enterprise-clients (1809) receive their Windows- and Office-updates from our WSUS. But in too many cases and for a long time now we or users noticed that updates are downloaded on the clients but not installed. Some users receive (or notice) a notification, click on the icon in the information-tray and can see a often very long list of missing updates (which are downloaded on the client but not installed). The users themselves can start the installation process.
Windows Update itself (checking for updates against MS-server) is disabled by policy.
We are using a WSUS-client-tool which is part of our software- (and hardware-) managing tool (Matrix42 Empirum). It seems that other customers don't have that problem. Usually every Tuesday this tool is automatically started - to check several times for updates and install them.
Is there a possible reason for that behaviour?
