Here is a script that I use to show WMI classes. I think you’ll find it useful. There is an example after the script: <\/p>\n

# Show-WmiClass – Show WMI classes

# Version: 1.0
# NOTE: Notice that this is uses the verb SHOW vs GET. That is because it
# combines a Getter with a format. SHOW was added as a new “official
