Answer: You have to edit the registry. These are the tips from jacky. Apparently they work for many but not all users:

In HKEY_CLASSES_ROOT\Folder\shell\explore\command I changed the default value from "%SystemRoot%\Explorer.exe /e,/idlist,%I,%L" to "D:\Program Files\XYplorer\XYplorer.exe %L"
And in HKEY_CLASSES_ROOT\Folder\shell\explore\ddeexec I emptyed the default value (org="[ExploreFolder("%l", %I, %S)]")
Seems that it's usually the ddeexec that is used, so if you dont remove it it's still explorer that is used. Once removed, the explore/command will be used, so XY will be launch.
You gotta know though that it might "break" some things. For instance when you open the control panel it's actually done inside Explorer, so now it would just start XY. You can still go to your control panel by starting explorer and going there.
