Update-Help through Authenticating proxy

After installing Powershell 4.0 it's a good idea to update the help files, but if your behind an authenticating proxy like me (at work at least) here's a quick way to get things updated.

The error displayed:
PS C:\Windows\system32> Update-Help

rShell.Diagnostics, Microsoft.PowerShell.Host, Microsoft.PowerShell.Security, Microsoft.PowerShell.Utility, Microsoft.W
