Windows 10: How can I "unlink" two computers

i have two laptops, one of the laptops is new. When setting up my new laptop, I used the same microsoft account as the old one. now, every time I install something on one, it will appear on the other one too. the backgrounds always change together as well, and it is becoming really really annoying. is there a way for me to turn this off?

I go thru the suggested steps: Start - Settings - Phone - Unlink this PC.
