Excellent Chris. And if WMI is disabled by the administrator, the same function can be used using API calls.

Mike - thanks for the star

Your point about WMI being disabled is a good one and the FAQ has been amended accordingly.

For those admins who love to 'tinker', (I have a less delicate word for that ), with systems

Windows Management Instrumentation Service

Provides a common interface and object model to access management information about operating systems, devices, applications and services.

If this service is stopped, most Windows-based software will not function properly.

If this service is disabled, any services that explicitly depend on it will start to fail.

If this service is stopped, most Windows-based software will not function properly.

You are not suggesting that if WMI is disabled, that most Windows-based software will not function properly.?

If so I would disagree with that.

The quote was from Microsoft - it can be found more than once on the net.

See one source of the quote here, note the real world description,

If you don't want your computer to work, set this to Disabled.

and one effect of disabling WMI here from Microsoft.

Chris.

My mistake. I was thinking of Windows scripting rather than WMI. You are totally right.
