In PowerShell 4.0 and better, there is a new alternative to the Where-Object cmdlet:
$all = Get-Service $all | Where-Object { $_.Status -eq 'Running' } $all.Where{ $_.Status -eq 'Running' }
The Where() method is special and does not need the outer parenthesis. It simply needs a script block to iterate. There is also a Foreach() method that works like ForEach-Object. The main difference between the classic cmdlets and the new methods is the way they are executed: the methods do not use a pipeline. So the overhead should be less.
