I've done clean installations of Win 7 with SP1 x32 (MSDN iso) on both virtual and real systems, and all of them report Even 10 WMI errors in event viewer on every boot. After googling it seems that this is a known issue with previous versions of Windows, (Microsoft Support), although all my pre-SP1 Win 7 machines actually do not have this error. What I would like to know is, has anyone figured out a real fix? It doesn't seem to affect system stability, but it's rather annoying to see error reports flooding the event viewer.
