Exchange 2013 remote session running as PowerShell version 2.0. How can I get it to run version 3.0?

Question

I'm trying to use the newer Powershell 3.0 features, particularly the ability to disconnect/reconnect a remote session, for our Exchange 2013 administration tools.  I have 3.0 on my workstation, and am connecting to a remote session on an Exchange 2013
server (on Server 2012).   Even LOCALLY on the Exchange 2013 server Exchange Management Shell I get the same behavior:
Exchange Command Shell on an Exchange 2013 server (running Windows Server 2012)

How/where can I force the Exchange session to run version 3.0?
Thanks in advance,

I still can't get it to work that way. I changed my cfexecute to:
<cfexecute name="C:\windows\system32\cmd.exe" arguments="/c C:\Inetpub\wwwroot\captcha\#cmd_filename#" outputFile="C:\testoutput.txt" timeout = "90"></cfexecute>
And I changed my bat file to have:
<cfsavecontent variable="cmd_content">
cd\
TSC.exe /s "#newString#" C:\Inetpub\wwwroot\captcha\#FileName# Mary (for Telephone)
</cfsavecontent>
The output file is showing:
C:\ColdFusion9\runtime\bin>cd\
C:\>TSC.exe /s "3.....P.....4.....Z.....8.....U.....7.....X....." C:\Inetpub\wwwroot\captcha\3P4Z8U7X-105724.wav Mary (for Telephone)
I still can't get it to run the exe. I have watched the process list while running this and the exe doesn't show up. I tried cfexecute on the exe directly before trying the bat method, with hard coded arguments, and it still didn't work. I am so lost right now this makes no sense to me.
