For those who just installed Windows 10 Pro 64 bit and used Microsoft Toolkit to activate it, and let it get all the Microsoft updates, are you having problems?
KMS isn't a hack, it is designed by MS and taken advantage of here. There is nothing happening to the activation mechanism to cause any updates to be effected. If and when MS changes their KMS protocol, then things might not stay activated until a new KMS solution at MDL is updated to match the then and if new KMS protocol.
