Run PowerShell command from command prompt (no ps1 script)

Here is the only answer that managed to work for my problem, got it figured out with the help of this webpage (nice reference).

powershell -command "& {&'some-command' someParam}"

Also, here is a neat way to do multiple commands:

powershell -command "& {&'some-command' someParam}"; "& {&'some-command' -SpecificArg someParam}"

For example, this is how I ran my 2 commands:

powershell -command "& {&'Import-Module' AppLocker}"; "& {&'Set-AppLockerPolicy' -XmlPolicy myXmlFilePath.xml}"

Maybe powershell -Command "Get-AppLockerFileInformation....."

Take a look at powershell /?

Run it on a single command line like so:

powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile 
  -WindowStyle Hidden -Command "Get-AppLockerFileInformation -Directory <folderpath> 
  -Recurse -FileType <type>"
