Is there a way to start PowerShell in a specific folder from Windows Explorer, e.g. to right-click in a folder and have an option like \"Open PowerShell in this Folder\"?
Another option are the excellent Elevation PowerToys by Michael Murgolo on TechNet at http://technet.microsoft.com/en-us/magazine/2008.06.elevation.aspx.
They include PowerShell Prompt Here and PowerShell Prompt Here as Administrator.
