Custom .ADM Template

[tester125]

Hi all,

Am trying to create a custom .adm template, but can't locate too much help.
I'm trying to change the name of "my computer" to the actual name of the workstation.
Here's the registry key:
[HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}
and this is the value that I need to add:
LocalizedString:REG_EXPAND_SZ:%Computername%

also when I create .adm template do I add this setting to an existing template or a new template.

Thanks all.
