Not that easy me thinks,

found following entries in the registry holding my Computername :

HKEY_CURRENT_USER\Software\Microsoft\Windows Media\WMSDK\General\ComputerName
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SchedulingAgent\OldName
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\Checked Host Name

and many more !

Don't know if ammending the following will change them all [Confused]

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Computername\ActiveComputerName\ComputerName
