I have just started using Hyper-V, so need some pointers guys. I have created two VM's one based on Windows Server 2003 (X86) and the other Server 2008 (X64). I'd like to keep them as 'templates' to create new Server OS's from, can I do that rather than setting them up from scratch every time using DVD's / ISO's etc? Will I run into a problem with SID's etc as they will be based on these template images? Thanks in advance.
