How to Deploy WMI filters through PowerShell (4282136)

How to Deploy WMI filters through PowerShell

1. Create a new filter: $filter = new-item -path "VCRoot:\" -Name "Testfilter" -Queries @( "root\cimv2;select * from Win32_Bios" ) -ItemType WMIFilter

2. (optional) Check in the filter: $filter = $filter | select-checkin

3. Deploy the filter: $filter = $filter | select-deploy The filter remains in the checked in (available) state, although the object history in the GUI says "deployed".

Deployment through the GUI works, and deployment for GPOs in powershell also works.

We do not implement the administrative shortcuts in Powershell that we do in the UI. This is due to the fact that the Powershell commandlets are designed as stand alone commands and we leave scripting / automating actions to the user so that the user has complete control over the process. In the UI we call Request Approval and Approve for the user after we check that they have the admin privileges to do so as a convenience, in Powershell we cannot create a commandlet which calls other commandlets on the user as they may want more fine grained control over the process. If this was automated that control would not be possible.

When you do a deploy in the GUI, if you then look at Show History and select Events - Show All Events
You'll see that a deploy actually does a Request Approval, then a Approve, before the Deploy is Completed

a Deploy from Powershell, doesnt show the Request Approval, then a Approve

In order to deploy a WMI Filter, you need to add the following
$filter = $filter | Select-RequestApproval | Select-Approve | Select-Deploy

this then works and when you do the $fliter, the Version is increased and in the History  its all correct
