If you have disabled all those settings and that did not resolve the problem, on the adverts you see, is there the name of a website?
If so, the adverts are generated by your browser.
If you use the Edge browser, open Edge, click the 3 dots at the top right, and select Settings.
In the search box in Edge settings, type notifications.
On the right, select 'Notifications - Ask First'.
If there is a list of websites allowed to generate notifications, delete them all from the list, then restart (not shut down) your PC.
