Is RegDeleteKey() working to delete an entire tree? 
I haven't checked the documentation, but I thought 
we needed to use shell32.SHRegDeleteKey() instead...

I will check up for differences, but this deletes the entire key with 
subkeys and values from the marked key.

The behaviour of RegDeleteKey differs between NT and 9x, so SHDeleteKey 
and SHDeleteEmptyKey were created to make things consistent...  see the 
remarks section in the MSDN page for RegDeleteKey for more details:

I guess that's fine than. Our RegDeleteKey() and ReactOS's RegDeleteKey()
behave properly, so there's no point in an additional dependency just so
our regedit can delete trees recursively on Win9x. Attila, I think your
patch is fine as is.

No, it will break if you run with version set to NT. If you want it to
always work right you have to use SHDeleteKey or do the recursion
yourself.
