I have this annoying issue on my Windows 10 tablet, and because it is a tablet, I dont want something like this happening of course, that tiworker is doing something every once in a while, maybe once a week, or once every 2-3 weeks, maybe once every few day, suddenly taking 50%. And it takes about 20-30 minutes, afterwards it's finished.

When I look into Windows Updates, no update is taking place, nor is MS Store installing any app updates. So what is this tiworker doing every once in a while for so long, 20 minutes, eating 50% cpu? Task manager shows, that it has 1.8-2.8MB/s disk usage over this time, so its doing something.

I also looked into Windows Scheduler and I cant see any "active timers active".

Is there a way to debug, what tiworker is doing, and maybe deactivate it?
