Wouldn't [verification of Windows system files in an anti-cheating service for online video games] break every time a Windows Update comes through?
I imagine that such an anti-cheating service will switch to blacklist behavior on Patch Tuesday until the majority have provided the correct hashes of updated files to the anti-cheating service provider.
I haven't heard of this behavior before.
I've read reports of Punkbuster and Games for Windows Live applying something like this. From this post:
Wine could fully implement the Windows API - but how it return the same hashs, etc. for operating system files?? So it will **never** fully support such products as GFWL, Punkbuster, etc. (that can use low-level access to files to verify that the OS is "genuine").
