我如何找出（在Powershell）什么过程/什么使用最多的内存？
编辑：我想弄清楚如何使用Powershell找出什么是使用所有的物理内存的情况下，任务pipe理器等无法解释为什么所有的物理RAM用完了。 也就是说，我需要识别高速caching等使用的内存
这里有一个获取当前正在运行的进程信息的方法，并按工作集大小进行sorting
Get-Process | Sort-Object -Descending WS 将该输出分配给一个variables，它会给你一个结果数组，然后你可以写出数组的第一个成员（在这种情况下，它将是一个System.Diagnostics.Process对象）。
$ProcessList = Get-Process | Sort-Object -Descending WS Write-Host $ProcessList[0].Handle "::" $Process.ProcessName "::" $Process.WorkingSet
这里有另外一个快速和肮脏的脚本来使用WMI的Win32_Process提供程序从当前正在运行的进程列表中转储一些数据项：
$ProcessList = Get-WmiObject Win32_Process -ComputerName mycomputername foreach ($Process in $ProcessList) { write-host $Process.Handle "::" $Process.Name "::" $Process.WorkingSetSize }
这将列出PID（句柄），进程名称和当前工作集大小。 您可以使用WMI Process类的不同属性来更改它。
一个class轮find您最高的内存使用过程的名称
Get-Process | Sort-Object -Descending WS | select -first 1 | select -ExpandProperty ProcessName
