What are some common WMI queries
I'm building a C# monitor app which uses WMI to grab some performance details of a remote computer.

BaseEvent child classes, does size matter?
Hi If I make a new class which inherits from BaseEvent can I make it as large as I like? What's the practical implications of doing so?

Querying WMI class Win32_QuickFixEngineering returns mucho weirdo timestamps (C#)
Class documentation here. The InstalledOn property is supposed to have a timestamp of (well, duh) when the fix was installed. But the doc doesn't say what's the format.
