Get-Command将返回一个对象，该对象包含多个带有路径名的字段。

我最近发现Where.exe可用于PowerShell。

> Where.exe kubectl
C:\Program Files\Docker\Docker\resources\bin\kubectl.exe

字符串
这与PowerShell变量兼容，因此可以在编写脚本时使用：$path = where.exe notepad

“Get-Command”或“where.exe”的限制太多，它们不能用于所有程序.

    [string]$StringToSearch,
    [array]$Directories = @(
        "${Env:PROGRAMDATA}\Microsoft\Windows\Start Menu\Programs"
        "${Env:APPDATA}\Microsoft\Windows\Start Menu\Programs"
    ),
    [string]$TypeTargetFile = "exe"
)
$ShortCutArray = @()
$shellObject = New-Object -ComObject WScript.Shell
foreach ($Directory in $Directories) {
    $shortcuts = Get-ChildItem -Path $Directory -Recurse -Filter *.lnk
    foreach ($shortcut in $shortcuts) {
        $ShortcutObject = $shellObject.CreateShortcut($shortcut.FullName)
        if (($ShortcutObject.TargetPath -like "*$StringToSearch*.$TypeTargetFile") -or ($shortcut.BaseName -like "*$StringToSearch*")) {
