WMI viewer script for MSH (GUI)
I Like sometimes a quick overview of I WMI class,
the MSH script below adds the Function :
get-WMIDatagrid (GWD)
to MSH, with this function you can look at the Instances of a WMI Object in a Datagrid.
I will first grab all Instances of the Class and add all the properties to a DataTable.
then it will launce a form with a Datagrid linked to the Generated DataTable.
this gives you a quick overview of the Class and the instances.
for example :
MSH> GWD win32_share
gr /\/\o\/\/
PS as I get All the Data you can get problems with a few classes (for example the Eventlog) that have very much data in them.(but there are only a few of them)
