can't uninstall the selected softwares

Hi guys~

I am trying to uninstall programs using powershell.
I have the following script for that action.

$ListToBeDeleted = @("program1", "program2")
foreach($software in $ListToBeDeleted){
  $app = Get-WmiObject -Class Win32_Product | Where-Object {
    $_.Name -match "$softWare"

when I ran this script, it seemed that it was trying to delete the program since it took some time to come back to my prompt screen. No error was returned. However, when I looked at the list of the programs in 'Programs and Features', "program1" and "program2" are still there.
After I ran this script, I also got the following lines.
can anybody tell me what I should change in my script to completely delete "program1" and "program2" from my computer?

Start Powershell as "Run As Administrator" then try .\uninstall.ps1
