I don't follow what's going on here. I'm running current Windows 11 Pro, licenses purchased from one of the markets for under AUD$50, and turned off all the standard annoyances via setting toggles and never see an ad or weather report etc.
Or get an edition that doesn't have all of that to begin with, and is supported for 10 years so you don't have to worry about updates mysteriously resetting the annoyance settings that you've disabled, or randomly breaking stuff.

You've probably wasted the 50 bucks. A valid product key a license does not make. Those cheap keys are usually ones for OEM licensing. If that is the case, you do not have a license.
Systems are snappy on 6th gen i7 laptops.
