Rename registry key

[JohnL]

How can I rename an NT registry key using the Win32 APIs without doing a tree copy of all the keys and values below it.
I want to be able to rename a whole branch, as a backup, before writing the new contents of the branch.

i am not aware of this functionality.

try the RegReplaceKey, RegSaveKey APIs

Where did you find this functions? Is there any documentation for them? I try to find them in the MSDN, but I can't find nothing.
Thanks for your time.

of course MSDN!
these are pretty old suckers.
RegReplaceKey requires NT 3.5...

[Lothar Haensler]

and...
do a DUMPBIN /exports of advapi32.dll.
They really exist :-)

Thanks, I made the dump, I saw that it exists. I also find the .h file...but in the MSDN I still can't find them. I think they forgot to include them.

The RegReplaceKey and RegSaveKey APIs backup and restore registry subtrees from files which may be what I have to do. What I would like to do is open a key using RegOpenKeyEx and rename the key that was opened.

e.g. Open the key \\HKEY_LOCAL_MACHINE\Software\Company\ProgData and call an API to rename the opened key to ....\ProgData_OLD.

The NT regedit program allows this, right click on a registry key and select rename. Internally it may copy the whole subtree to a new tree with the new name then delete the old subtree. I am beginning to think this is the way it must work.
