I have this script to list all installed applications
[cmdletbinding()][cmdletbinding()]
param(
[parameter(ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$true)]
[string[]]$ComputerName = $env:computername
)
begin {
$UninstallRegKey="SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall"
}
process {
foreach($Computer in $ComputerName) {
Write-Verbose "Working on $Computer"
if(Test-Connection -ComputerName $Computer -Count 1 -ea 0) {
$HKLM = [microsoft.win32.registrykey]::OpenRemoteBaseKey('LocalMachine',$computer)
$UninstallRef = $HKLM.OpenSubKey($UninstallRegKey)
$Applications = $UninstallRef.GetSubKeyNames()
foreach ($App in $Applications) {
$AppRegistryKey = $UninstallRegKey + "\\" + $App
$AppDetails = $HKLM.OpenSubKey($AppRegistryKey)
$AppGUID = $App
$AppDisplayName = $($AppDetails.GetValue("DisplayName"))
$AppVersion = $($AppDetails.GetValue("DisplayVersion"))
$AppPublisher = $($AppDetails.GetValue("Publisher"))
$AppInstalledDate = $($AppDetails.GetValue("InstallDate"))
$AppUninstall = $($AppDetails.GetValue("UninstallString"))
if(!$AppDisplayName) like Landesk { continue }
$OutputObj = New-Object -TypeName PSobject
$OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $Computer.ToUpper()
$OutputObj | Add-Member -MemberType NoteProperty -Name AppName -Value $AppDisplayName
$OutputObj | Add-Member -MemberType NoteProperty -Name AppVersion -Value $AppVersion
$OutputObj | Add-Member -MemberType NoteProperty -Name AppVendor -Value $AppPublisher
$OutputObj | Add-Member -MemberType NoteProperty -Name InstalledDate -Value $AppInstalledDate
$OutputObj | Add-Member -MemberType NoteProperty -Name UninstallKey -Value $AppUninstall
$OutputObj | Add-Member -MemberType NoteProperty -Name AppGUID -Value $AppGUID
$OutputObj# | Select ComputerName, DriveName
}
}
}
}
end {}
I tried to use this: .\Get-InstalledSoftware.ps1 -ComputerName computer01 | ? {$_.AppName -eq “APPGUID HERE” } |
How can I list just a particular installed software. I want to query all computers to see if an antivirus is installed and what version it is.
