A Microsoft spokeswoman said there is no Windows Server 2003 mechanism for disabling software identified as having been installed using a stolen code. In theory, such a mechanism might be capable of disabling software during a routine update with one of Microsoft's Web servers.Windows XP's first service pack wouldn't install on systems using widely-leaked corporate keys, so that's nothing new. However, if the "future updates" Microsoft refers to include critical updates and security patches, pirates will have to work harder to stay one step ahead of the Redmond software giant.
Those copies of the software installed using the leaked code "won't be able to install future updates or service packs of access Windows Update," the spokeswoman said.
It seems unlikely that Microsoft will ever be able to halt the flow of legitimate corporate keys onto the Internet, but it's certainly within their power to force pirates to acquire a fresh key for each new Windows Update download. Then again, it's probably only a matter of time before someone releases a utility that can generates corporate keys on the fly. Such a utility already exists for Windows XP, and it's effectively killed Microsoft's ability to police corporate keys.
