Hehe, yes. Typical M$. Similar to 7,376,970: (May 20, 2008)

Abstract
"A system, method, and computer readable medium for the proactive
detection of malware in operating systems that receive application
programming interface (API) calls is provided. A virtual operating
environment for simulating the execution of programs and determining if
the programs are malware is created. The virtual operating environment
confines potential malware so that the systems of the host operating
environment will not be adversely effected. During simulation, a
behavior signature is generated based on the API calls issued by
potential malware. The behavior signature is suitable for analysis to
determine whether the simulated executable is malware."

Sounds like a 'sandbox', see http://www.aladdin.com/eSafe/, available
since 1999 or so. (for instance)
