Can't activate windows

[PlushBac0n69]

I recently stopped using kms pico as i was getting this weird bug that kept prompting me that my windows liscense was going to expire soon whenever my wifi was either slow , or had disconnected. "No problem!", i said as i went on amazon and bought a product key online. For some reason it said that my windows was indeed activated, so i went and ran slmgr /upk and a few other commands that did something like remove the activation key. Then i tried to enter the windows key but it said "The product key you entered didn't work" (0xc004f050) so i thought "maybe the key was broken so i contacted the seller. After a bit of talk, the seller had already given me three activation keys which all didn't work. I knew it was probably something up with my software and i didn't know what. I don't want to waste this amazon seller's time and my 8.50 bucks on this key. also every time i restart it still says i have a product key which i don't remember installing. 
Specs (in case these might be the problem) : 
CPU:5600X
GPU: Asus dual 3070

Mobo: TUF gaming B550 plus

You'll have to reinstall clean.
