Renaming registry

[sagmam]

Is there any way to rename a regsitry key that already exists? The same way a user can do when he presses F2 while in the Registry Editor? I could not find any Win32 API function that does this, nor an automation interface of regedit... /=/=/=/= Deus /=/=/=/=

There is no such way. Regedit at first creates new key, copies all subkeys, and then deletes old key.

I find it hard to believe since it is done instantaneously - even if the renamed key contains a full hierarchy. Try it yourself: create some huge subtree and then rename its root key. You'll see that it happens immediately. /=/=/=/= Deus /=/=/=/=

When I do that my program works very fast too :))) ..And why you suppose it works slowly? Most of Registry is cached in memory therefore it's just memory copying. But if you don't believe me, run Regmon and see for yourself
