The few times I needed a key, it worked the first time. And for a friend who needed Win11, the upgrade from 10 Pro to 11 worked first time.
I'd never pay more than $5 per Windows key. But I prefer Linux instead.
"Oh, you need more backup space! Take this special offer now for more storage, only $NN a month".
But with the horrendous performance and scam behavior, Ive heelped others to Linux to really good effect.
Just theres that 1 person who *needed* Windows and all the abusiv behaviors it inflicts. It was more akin to "Executives dont get fired for recommending IBM/Microsoft", and a utter refusal to try something better. Theyve been a friend for 2 decades, so I gave them the warning, but did help them.
Grey market means the codes often work (valid KMS generation etc) because they match the algo,
and or were validly issued to a manufacturer,
but that doesn’t make them “100% legit”.
Otherwise you wouldn’t be saying “grey market” - it would just be the market.
