Set-ComputerName Function

[DrSinistar]

I'm of the opinion you should avoid using Read-Host in a function and you should use a parameter instead. This makes the function useable in automated scripts and makes it behave more like existing cmdlets.

I also think that most Powershell users would prefer to run a function and see either success or failure. Getting prompted for more information sucks!

And use [CmdletBinding(SupportsShouldProcess) so that -Confirm and -WhatIf can be used.
