Where Microsoft.SharePoint.PowerShell.dll Is

I had this come up with a developer at a client that was trying to build some administrative tooling for their internal development environment. After looking all through the SharePoint environment, I found it actually doesn’t exist anywhere besides the GAC by default. If you need to export it, you can just open a command prompt, navigate to c:\windows\assembly\gac, go into the GAC_64 directory, open the directory for the PowerShell assembly, then run a copy command to your desired directory.
