Q. What is & in PowerShell?

A. & is the call operator that will execute code. Normally we just execute cmdlets as their name is in the search path however consider you save commands in a string and want those commands to execute. The call operator will do that. For example:

PS C:\> $commandstorun = "get-host"

PS C:\> $commandstorun

PS C:\> & $commandstorun
