Windows 7: Registry : How to add extension keys through command line

Registry : How to add extension keys through command line

I am looking for some help:
I wish to add a new extension key of type .dns
If I execute :
reg add HKEY_CLASSES_ROOT\.dns
Then the key .dns does not get added to HKEY_CLASSES_ROOT but somewhere in HKEY_CURRENT_USER ?
How do I get the command to add the .dns key to HKEY_CLASSES_ROOT ?
What command should I execute?

Thank you

HKEY_CLASSES_ROOT is just an alias to HKEY_LOCAL_MACHINE\Software\Classes, and using both is exactly the same.

Most likely, it's just a permission issue. HKEY_CLASSES_ROOT is a system-wide key that, by default, is read-only to non-admins. To change it, you must run the commands in an elevated command prompt, or run regedit as administrator, otherwise the write will be virtualized to HKEY_CURRENT_USER, into the VirtualStore, or just fail with an "access denied".
