Template Update Script Not Finishing

[pamiller21]

I have a script that takes a template and converts it, updates the windows, then converts it back.  Script works great with Win2016 & 2019, but I had to make a win10 template and it won't convert it back.  Looking at it and I think the problem is that the VM will not start vmtools until someone logs into it and the script is designed to turn off the vm once it sees the tools are initialized.  I don't know what's going on in Window's world that makes this fail but unless I can find a magic wand to make it work I am thinking about making the script just ignore that and continue on.

Script:

#Update Template Parameters

    #Update Template Name

    $updateTempName = "TempWin10"

#---------------------

#Update Template

try {

    #Get Template

    $template = Get-Template $updateTempName

    #Convert Template to VM

    if($showProgress) { Write-Progress -Activity "Update Template" -Status "Converting Template: $($updateTempName) to VM" -PercentComplete 5 }

    [void]$log.appendline("Converting Template: $($updateTempName) to VM")

    $template | Set-Template -ToVM -Confirm:$false

The VMware Tools are normally configured as a service which start automatically when the OS starts.

Did you check that?

You seem to wait 90 seconds in the script after the async power on.

Is that time long enough?

Why not wait till the GuestOperationsReady (in GuestInfo) says $true?

There are several examples of using that property available in this community.
