Question

im试图在计算机上执行此功能。来源：https://github.com/gangstanthony/PowerShell/blob/master/Get-InstalledApps.ps1

我将其放在一个名为Get-InstalledApps.ps1的文件中，并试图在Windows 10上提升权限的命令提示符下运行它，但没有任何反应。如何正确调用该函数？如果我将整个函数复制粘贴到外壳中，它将起作用，但这不适用于我的用例，因为我正在尝试使用WPKG远程执行它。

Get-InstalledApps -ComputerName $env:COMPUTERNAME

https://github.com/gangstanthony/PowerShell/blob/master/Get-InstalledApps.ps1
example usage
    Get-InstalledApps -ComputerName $env:COMPUTERNAME -NameRegex '^java'
you will get an uninstallstring returned from that as well. you can use one of the methods below to run the uninstaller on the remote computer

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
                    }
                }
            }
        }
    }
}

更新：解决了它，我应该在脚本文件的末尾添加 Get-InstalledApps-计算机名$ env：COMPUTERNAME

将函数放在文件中并调用它
