Where does this message come from?

Whenever I start my laptop (Windows 10), I get this message:

And a few more.

What does this mean and how can I fix the error?

Is from the program ActivDriver look at programs if you need to reinstall the stuff, otherwise uninstall.

Use the ProcessExplorer: https://docs.microsoft.com/...s-explorer

Start it. Drag the crosshairs from the tools bar to the window with the error message and you will be shown which program has generated the window.

OK thanks. I will try it.
