PowerShell directory find command?

Hello,
I have a question about what is the command to use in order to display the location of a file that can be run trough PowerShell.
For example if you type in the console "mf.msc" is starts, but how can I see where this file is located?
If I type Get-Location PS displays the current directory, not the location of the file I'm looking for.
Thank you.

You're probably better off asking this on a windows / computer forum.
