If you see any applications using an unusually high percentage that does not decrease within a few minutes, you may need to troubleshoot this program for errors or reinstall it. If most of the time, the CPU usage is 100%, it seems your PC is trying to process more tasks than it can.
Finally gave up on windows update and installed “WSUS Offline Update”, an open source updater intended to build update files for use without an internet connection.
