Get list of installed software of remote computer

Question

Is it possible to get a list of installed software of a remote computer ? I know to do this for a local computer with use of Powershell. Is it possible with Powershell to get installed software of a remote computer and save this list on the remote computer ? This I use for local computers: Get-WmiObject -Class Win32_Product | Select-Object -Property Name

Thanks in advance, Best regards,

This uses Microsoft.Win32.RegistryKey to check the SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall registry key on remote computers.

*edit: pasting code for reference

function Get-InstalledApps {
    param (
        [Parameter(ValueFromPipeline=$true)]
        [string[]]$ComputerName = $env:COMPUTERNAME,
        [string]$NameRegex = ''
    )
    
    foreach ($comp in $ComputerName) {
        $keys = '','\Wow6432Node'
        foreach ($key in $keys) {
            try {
                $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $comp)
                $apps = $reg.OpenSubKey("SOFTWARE$key\Microsoft\Windows\CurrentVersion\Uninstall").GetSubKeyNames()
            } catch {
                continue
            }

            foreach ($app in $apps) {
                $program = $reg.OpenSubKey("SOFTWARE$key\Microsoft\Windows\CurrentVersion\Uninstall\$app")
                $name = $program.GetValue('DisplayName')
                if ($name -and $name -match $NameRegex) {
                    [pscustomobject]@{
                        ComputerName = $comp
                        DisplayName = $name
                        DisplayVersion = $program.GetValue('DisplayVersion')
                        Publisher = $program.GetValue('Publisher')
                        InstallDate = $program.GetValue('InstallDate')
                        UninstallString = $program.GetValue('UninstallString')
                        Bits = $(if ($key -eq '\Wow6432Node') {'64'} else {'32'})
                        Path = $program.name
                    }
                }
            }
        }
    }
}
