More than 100 million users connect to nProtect GameGuard daily through more than 300 gamesFact|date=October 2008. Some editions of GameGuard are now bundled with INCA Internet's Tachyon anti-virus/anti-spyware library, and others with nProtect KeyCrypt, an anti-keylogger software that protects the keyboard input information. nProtect GameGuard hides the game application process, monitors the entire memory range, terminates applications defined by the game vendor and INCA Internet to be cheats, blocks certain calls to DirectX functions and Windows APIs, and auto-updates itself to change as new threats surface. nProtect GameGuard is launched via GameMon.des with a driver dump_wmimmc.sys.

Issues with GameGuard

There are issues with GameGuard regarding problems with other programs. Many of the problems have been solved or are in the process of being resolved. The nProtect GameGuard FAQ page is shown below in the External Links section.

Because of its method of actuation (very similar to a rootkit), it is criticized for being extremely invasive, often without knowledge of the end user. The software installs a device driver which is difficult to uninstall; even uninstalling the game will still leave some files hidden on the system, but it stays inactive without the game. In recent versions (revision 1007 and up), GameGuard fails to halt when the game ends, so GameGuard continues to use computer resources and inject code into processes. This is often unknown to the end-user, as GameGuard masks its CPU usage by hooking Windows system querying APIs. Most anti-virus vendors currently exclude nProtect GameGuard from their detection databases due to it being commercial software, however this was initially not the case, leading to system crashes as both the Antivirus and GameGuard attempted to override each other.

Many hackers attempt to find ways to compromise GameGuard in new ways. For example, it has been said that GameGuard can still be compromised by using modified game client files, modified versions of Cheat Engine coupled with server emulation utilities. nProtect GameGuard constantly updates itself and provides new protection against the latest threats. Even though it boasts such effectiveness, in truth hackers can break or bypass GameGuard faster than it gets updated, therefore rendering the system quite useless. Especially from the number of sites out there utilizing 'bot' programs to flood the game to farm the ingame currency & rare items, which are then sold for real money. Such sites and 'bots' have been known to be up and running again, having bypassed GameGuard, within an hour of its latest update.

On some games such as MapleStory, the game itself does a hash check of the GameGuard revision currently running and will exit if it does not match the hash on the server side. This is a security measure from nProtect GameGuard to ensure that GameGuard has not been hacked and nProtect GameGuard should update to the latest version under normal circumstances.

Because of the way that GameGuard hooks into core system DLLs, it is impossible to run games protected by GameGuard under a replacement Windows API, such as Wine.
