The illegal Windows 8 copies were activated through a simulated KMS activation server. The KMS workaround only offered a six month period until Windows required another activation. But activating Windows through a third party Key Management Services server has its downside. A Windows copy can only be activated for a maximum period of 180 days.
When pirates were still thinking on how to beat Microsoft’s activation system, Microsoft unknowingly provided a solution. Microsoft’s intent was to offer a free Media Center upgrade to Windows users that owned a Windows 8 Pro license. The giveaway is valid until January 31st. Pirates updated their pre-activated Windows 8 copies to a fully activated Windows 8 version with the help of Microsoft’s own Media Center upgrade offer.
