Windows Power Shell does not know psae

I’ve never notice it before, probably already known by most of you guys. But whilst I was building a Peoplesoft database from within Windows 2012R2, I ran psae (PSADMIN AppEngine) from a Windows Power Shell command prompt.
And here what I got:

PS E:\pt854\bin\client\winx86> psae
psae : The term 'psae' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ psae
+ ~~~~
    + CategoryInfo          : ObjectNotFound: (psae:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Suggestion [3,General]: The command psae was not found, but does exist in the current location. Windows PowerShell does
    not load commands from the current location by default. If you trust this command, instead type ".\psae". See "get-help
    about_Command_Precedence" for more details.
PS E:\pt854\bin\client\winx86>

Well, probably not a big deal, but good to know and worth a try what is recommanded, since I trust this psae command:

PS E:\pt854\bin\client\winx86> .\psae
Invalid command line argument list.
  process command line:
  GUID command line   : <unavailable>
Usage:
    psae -CT <dbtype>
         -CS <server>
         -CD <database name>
         -CI <connect id>
         -CW <connect password>
         -CO <oprid>
         -CP <oprpswd>
         -R  <run control id>
         -AI <program id>
         -I  <process instance>
         -DEBUG <Y|N>
         -DR <Y|N>
         -NOCOMMIT <Y|N>
         -TRACE <value>

         -TOOLSTRACESQL <value>
         -TOOLSTRACEPC <value>
         -OT <output type>
         -OF <output format>
         -FP <file path>
  or
    psae <parmfile>
PS E:\pt854\bin\client\winx86>

Of course, we can also still use the good old Windows DOS cmd :
PS E:\pt854\bin\client\winx86> cmd
