Hi Robin

In one of our build agents, there is a weird issue about shell/batch step:

I select specific agent, it's a windows machine, and the machine has multiple Python versions installed. When I go to the machine directly, and use command prompt to execute "python --version", the machine itself by default uses 3.6.3

And there is another python, 3.6.5. For some reason, when I execute "python --version" in a shell/batch step, Quickbuild specifically uses this version, it reports 3.6.5. Now that I uninstalled this version on that machine (redundant, not needed), quickbuild doesn't even recognize python command anymore.

C:\buildagenttest\workspace\root\Sandbox\testsss>python --version
19:21:55,768 WARN  - 'python' is not recognized as an internal or external command,
19:21:55,769 WARN  - operable program or batch file.
19:21:55,873 INFO  - Executing post-execute action...

Command return code: 1
Command error output: 'python' is not recognized as an internal or external command,

I thought Quickbuild is supposed to control a CMD on that machine, that's all. But why does it behave differently with a CMD directly on that machine?

Thank you for your help!
