It's probably Very Good, but one Microsoft-thing one should be aware of: using 
WMI functionality generally starts up a background WMI service...

Similarly, starting the standard clipboard viewer (discontinued in Windows 
Vista) starts up a silly copy-clipboard-contents-over-network service.

On a low-range machine the WMI service can be a resource concern.

I don't know whether the WMI service is a security concern (it probably is, 
considering IIS and anything Microsoft+Network and that WMI is meant to 
administrate machines over network, it's an enterprise thing not a personal 
computer user thing), but the clipboard service is, as I recall, a concern.
