For starters sounds like you have the Windows 10 S-Mode operating system. S- mode locks your system down so you can only use Microsoft software and apps from the Microsoft Store.
Your computer came with Microsoft Edge as a web browser and that one brings in all the ads from the venders microsoft is assiciated with, and other sites that you have visited in the past, by associating you with your IP Address that brings the service into your house.
In Firefox you can decline to accept any cookies, and surf the web in Strict mode and the annoying ads will stop. You have to go into it on setup and make your selections and tighten up your security.
Now you set Firefox as your default browser.
Now to get rid of Edge and download and install the better Firefox browser by Mozilla, you first have to sign up a new account with Microsoft, (like a free outlook.com email address) then you can sign in and go to the Microsoft Store and get the free fix to unlock your S-Mode computer. (Now they have your name and an e-mail address associated with you and your computer . . Let the Tracking begin, without your permission.)
Sounds like your new computer is a good candidate for the Linux Dual boot OS. You can go into Windows 10 once it is unlocked from S-Mode, and shrink the partition to half the size of the hard drive. Then you or your computer tech can Install Linux 19.2 right on top of windows 10.
Linux will be the main default OS, and can be set up like a windows 7 desktop if you like that layout, and have Firefox as your main browser. Soon you will find out you really don't need the confusing microsoft anymore.
Good luck on your 2020 computing quests. I feel sorry for people getting the new 10 systems, no way secure, and a pain to use.
