PowerShell 技能连载 - 查询当前登录的用户名

有两种方式可以查询当前登录的用户：

# User logged on to a physical box
Get-WmiObject -Class Win32_ComputerSystem | Select-object -ExpandProperty UserName


# Owners of explorer.exe processes (desktop is an Explorer process)
Get-WmiObject -Class Win32_Process -Filter 'Name="explorer.exe"'  |
  ForEach-Object {
    $owner = $_.GetOwner()
    '{0}\{1}' -f  $owner.Domain, $owner.User
  } |
  Sort-Object -Unique

两种使用 Get-WmiObject 的方式都支持本地和远程方式调用。
