Powershell outputting string but not executing

Question

Powershell outputs the string instead of executing command.

$apps = @()
$apps += Get-ItemProperty "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*" # 32 Bit
$apps += Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*"  

$apps365 = $apps | Where-Object {$_.DisplayName -Match "365" | Sort-Object DisplayName}



$uninPaths = @()
foreach ($item in $apps365) {
    $uninPaths += "& CMD /C "+$item.UninstallString
}

Invoke-Command -ScriptBlock{$uninPaths}

What makes you believe that the uninstall string requires to be run in cmd.exe? Usually the unistall string is a standard executable file which often accepts one or more arguments/parameters. They do not need to be exectuted in that specific CLI interface. Why not just try it directly in the PowerShell CLI interface, you're already using? — Compo

$uninPaths is just a string. To execute it like a command, you can feed it to Invoke-Expression:

Invoke-Expression -Command $uninPaths

Invoke-Command is generally used for running powershell commands on remote machines.

Even with 'Invoke-Expression' it is only outputting the strings but not executing the commands.
