activating windows 10 with key bought online

[LiberatedPudding]

The version of windows 10 i'm using is currently pirated and recently has noticed it, I was looking online for where to buy cheap windows 10 pro keys when i found this site http://www.onlinekeystore.com/buy-windows-10-professional-oem-key-direct-download.html
I was wondering if anyone can tell me if this is a legitimate way of buying a windows 10 key and if i can simply insert the windows 10 key that comes with this product into the current windows 10 i'm using that is unauthenticated? thank you in advance.

The safest place to buy win 10 from is Microsoft store - buy the download version and they will send you a link to download file and the licence key in an email. simply enter that licence key into settings/update & security/activation

you can probably buy it cheaper elsewhere but the safety of the licence being legit goes down as the price does.

Yeah it's safe. It'll just be an OEM key.

use the retail key as you can take it with your hard drive as the oem key binds the licence to 1 motherboard

It's 'safe' BUT you'll be back at somepoint saying that it has expired. Buy it properly.
