Wildkilla's keys is MSDN

Wildkilla has been selling Window 7 keys and it works. But what people don't know is that the keys are MSDN, which are not retail and legit. The key will be disabled once microsoft notice is not used for development uses. Heres one of the keys I bought and through the Microsoft key checker it shows is distributed through the MSDN channel.

Picture says it's a retail license type.

 

yes. but if u search about msdn, the channel that distribute it truly affects it, because right now is retail, but anything that wildkilla do will affect the code.
