  • Why would you want to do this?

    Please read the help for the PowerShell command line:

    powershell /?

    Always start by reading the help.  Without any understanding of what a command is or how it works you will get nowhere by guessing.

  • One thing you will not understand as you are not a Powe4rSHell scripter.  The quoting rules for commands and for PowerShell.

    To get an understanding of that you can  also read this help from PowerShell.

    help about_Quoting_Rules

    When running utility programs it is not necessary to use "Start-Process".  Just call the command directly.


    powershell -command "notepad"

    powershell -command "runas ..."

  • It works with single quotes.  Cmd (or powershell) will take off the double quotes unless they're backslashed. Or put it in a script.  Or pass -argumentlist as an array.

    powershell Start-Process -Verb runas cmd '/k dir c:\'

    powershell Start-Process -Verb runas cmd \"/k dir c:\\\"

    powershell Start-Process -Verb runas cmd /k,dir,c:\

  • Hi jzhao2007,

    Prepend a backslash \ to the doubel quotes “ and backslash \ to allow them to be treated as ordinary text.
