I just want to write a script will check that any of the following script is running or not. i tried what you suggested and still it is not working properly. Here is my 

 

ForEach($App in $AppsList) {

$software = (Get-AppxPackage -allusers $App).PackageFullName
$installed = (Get-ProvisionedAppxPackage -online | Where {$_.DisplayName -eq $software}) -ne $null

Write-Host "'$App' not found.";

For starters the PackageFullName property is different from the DisplayName one, so you should not be comparing them directly. The Get-ProvisionedAppxPackage lists apps that are included in the windows image, not necessarily ones that are installed. If you only care about the installed ones, use just Get-AppxPackage, which will cover any app, regardless of the source it was installed from (as mentioned above, some will be directly downloaded from the internet).

    Hi VasilMichev

     

    As you said i am using only get-Appxpackage but still its not working how it suppose to work. i have a list of package which need to be find apps is installed in pc but some application is not installed and it still says it is installed.

    $PackageFullName = (Get-AppxPackage -allusers $App).PackageFullName
    write-host $PackageFullName
    if ($PackageFullName)
    {
    Write-Host "Removing Package: $App"
    }
    else
    {
    Write-Host "Unable to find package: $App"
    }

      Here is the update code
      $PackageFullName = (Get-AppxPackage -allusers $App).PackageFullName
      write-host $PackageFullName
      if ($PackageFullName)
      {
      Write-Host "Package found : $App"
      }
      else
      {
      Write-Host "Unable to find package: $App"
      }

        As Vasil wrote, don't use PackageFullname. Use DisplayName.

        Here is a script I run during computer deployment:

         

        [CmdletBinding()]
        Param()
        ##
        ## Remove everything but StickyNotes, Paint, Photos, Calc
