Finding Powershell Assemblies

I have been having problems with the Start-Transcript command working on some machines and not on others (particularly within Jenkins CI machines). The error message was not very helpful:

so I thought it would make sense to try to find the assembly and see what it's trying to do when it fails.

Using Get-Command was the obvious choice but doesn't seem to help.

Get-Command Start-Transcript

Then I discovered the Format-List cmdlet that takes the default output and expands it to show all the properties.

Get-Command Start-Transcript | Format-List \*

Voila! the location of the assembly so I can hunt down the error with IlSpy.
