scripting languages native to windows for remote users support

Question

I work for a application dev company but I am in the support side of it. I am looking to run scripts on to remote-host (logmein Rescue Technician Pro). Our clients all run windows machines and the oldest OS version we support is XP SP3 and the latest win8. I need a scripting language that is native to windows and doesn't require any download this or unzip that. These scripts are Powershell scripts but as we all know the executionpolicy needs to be set to unrestricted. I need a scripting language that automates mouse clicks and keystrokes like hitting enter on the keyboard or typing words into cmd/Powershell, then hitting enter for example. I am trying to run a script in another language to disable the excutionpolicy in Powershell and then start the powershell scripts from this point. I hope I have explained myself.

UPDATE:

I am bad at what I am trying to explain I guess. I need to run a script to disable ExecutionPolicy on remote users through LOGMEIN RESCUE TECHNICIAN. Logmein has a tab called "SCRIPTS" that automatically startup when you connect to the remote session. The problem is that PowerShell by default is set to executionpolicy restricted. That will not allow my scripts to run and I have to run them manually from my machine, I believe their is a way to just run the scripts and have them out put the results to me without having to pull up the remote users GUI, all the computers are their own independent machines and not on a domain. I need to run the scripts as unrestricted on the remote machine on initiation of the remote session. Thats why I having going around in circles trying to figure this out. I was able to disable powershell from the cmd but i need to hit enter, i need to script the enter key stroke but again i keep running into blocks just run my scripts. I'm annoyed by this now at this point.

Answer 1

You can run a powershell script like so:

powershell -executionpolicy unrestricted -file "C:\Myscript.ps1" 

This will not change the global executionpolicy for the whole machine, but just to run that script.

Answer 2

Two options:

1.Stick with PowerShell. When you launch PowerShell, instead of launching from the shortcut, run the following command (either from a cmd prompt, or run command):

powershell.exe -ExecutionPolicy ByPass 

This will run PowerShell with the execution mode set to ByPass.

2.Use the old way of scripting that works on all versions of Windows, VB scripts. (although, after using PowerShell, VB scripts are hard to go back to)

Answer 3

I'd honestly go with JScript (or VBScript, but JScript is a much nicer language IMHO), since you don't want to have to install anything on the remote machines. XP doesn't include PowerShell, so you'd have to install it at some point.

WSH (Windows Scripting Host) languages like VBScript and JScript, and PowerShell can all simulate mouse clicks and keystrokes, but if you want one script that will run on all of those platforms out-of-the-box, you'll need to stick with WSH languages.

If you have any control over what gets installed on the remote systems, though, go with PowerShell, or - at very least - make sure that the Windows Scripting Host components are up to date with the latest release available for the platform. I'm not sure whether that would come as part of the typical Windows Updates or not.

Just my $0.02.
