Data from the computer are suddenly on the laptop?

I have a question, every time I install something on my computer, the files appear on my laptop. I have absolutely no idea how to do this and would therefore ask for advice here.

OneDrive?

Which dates? Apparently that has to be synchronized.

If you have a Google account on both machines, that would be a solution. Google uploads everything to a cloud if you don't turn it off.

Ohh I didn't even deal with that! I just deactivated it and now it is no longer displayed on the laptop.

Yes, I just deactivated it on the laptop and now everything is fine, thanks.
