Kinguin and G2A

[Crypt1c]

I've heard a lot of bad reputation from people buying windows key form them, anyone with experiences of key deactivating after a while? Or anyone who bought from them and it still works. I want to see the number of keys  that were later deactivated after purchase compared to those that didn't.

It's hard to keep track of deactivated keys from storefronts like Kinguin and G2A. Main reason why the keys get deactivated is that a vast majority were not meant to be sold, but rather used as OEM keys.

I usually stay away from G2A, they are just super shady in my opinion.

You will probably be fine if you buy from the them. While that is an occasional issue, from my understanding its pretty rare. That being said, i strongly recommend buying windows from a licensed retailer, such as Microsoft itself.

Can't speak for those 2, but the Win7PRO key I bought at Play-Asia a couple of months ago still works fine.

 

Normally I'm not a fan of grey market, but MS doesn't sell Win7 anymore and 8.1 and 10 aren't fully compatible with some of the programs I use.  So it was either grey market or buying a second-hand retail package at much greater cost and with the same risk.

You don't buy from them,you buy from people who sell stuff on their sites.

Buy your Windows key for an authorized Microsoft reseller and your will have no fear of your key being deactivated. Buying from a non-authorized source is the risk you take when purchasing a key for $20. You have nothing to moan about if is deactivated.

Of course that is only possible if the authorized reseller still sells the version you're looking for.
