Hi,

I am trying to do this action via Powershell.
http://blogs.technet.com/b/heyscriptingguy/archive/2011/12/14/use-powershell-to-find-and-uninstall-software.aspx

another link i was looking at is - http://stackoverflow.com/questions/113542/how-can-i-uninstall-an-application-using-powershell

However I cannot get this to work correctly.
Im not sure how the following command works..

$app = Get-WmiObject -Class Win32_Product | Where-Object {
    $_.Name -match "Software Name"
}

$app.Uninstall()

I tried this but the command was incorrect not sure what I should use for Software name/ Appname??
