This may be addressed with newer versions but for those still on 3.2.0......

While working with cm12 r2 clients and the install-sccmsoftwareupdates it would simply not work. After some digging I found that on line ~4748 the error out code line was wrong

Write-Log "Trigger SCCM Install Updates failed: " + $_.Exception.Message

It would always wing an error but changing it to

Write-Log "Trigger SCCM Install Updates failed: $($_.Exception.Message)"

solved that problem but now the error tells me that the System.Management.ManagementObject class does not contain installupdates.

The code originally pointed to:

$SmsSoftwareUpdates = [wmiclass]"ROOT\ccm:SMS_Client"

which does not contain the right stuff.

However,

$SmsSoftwareUpdates = [wmiclass]"ROOT\ccm\ClientSDK:CCM_SoftwareUpdatesManager"

does and now looks to be all happy happy.

Below is the whole function as I have it today.
