[PATCH 0/1] MR9303: ntdll/tests: Add NtRenameKey tests checking subkey after rename.
Add a test verifying that subkeys are correctly renamed and enumerated in the expected order after calling NtRenameKey. See merge request !9247. Signed-off-by: chenzhengyong <chenzhengyong(a)uniontech.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9303

I think using existing function is better. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9303#note_119942
I'm only curious, why have you thought that key order might change? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9303#note_119944
