I developed a KiXtart script to change all the Registry entries of a machine.
The script I believe works but I need to start manually REGEDIT to export (in text mode) the four main Registry subtrees HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS. I change all the entries I need and after I import the modified file using %COMSPEC% /C registry /S "myFileReg.txt".

I have got hundreds of machines to change and I can't automate the work because I'm not idea how to save the registry subtrees.

Please, help me.
Thanks

P.S. We need to save every subtree because the REGISTRY application doesn’t save the entire registry.
