I recently got a new PC, I already have a laptop that I would like to take with me. I recently noticed that the background image that I set on my new fixed PC was suddenly on my laptop. I never connected the computers together. When I got the new PC, the manufacturer automatically set a background that I could not find on the Internet, too, which suddenly appeared on my laptop. Why?
Have you signed up for the new pc with your microsoft account? Otherwise, I don't normally know something like that.
Windows 10 Settings Sync does it
If you use the same license for both and are registered with Microsoft online, the devices will be synchronized. You can also switch it off.
If you're one of the few Edge users (which I don't hope now),
then it also transmits all your passwords.
Yes, it is true.
