I can not change back to the default win explorer!

[Rem56445]

I am unable to change the file explorer back to the original file explorer. The checkbox in the settings is checked, but it still uses explorer ++. What registry key do I have to modify to get the original file explorer back, and why is it not working to change the explorer back in the options?

This has also hit me, but I also discovered why.

There's definitely something going on with having multiple Explorer++ windows open, then changing this setting in one of these, followed by everything going right/wrong depending on which window you close first (since it looks like it saves it settings on exit, while all the Windows registry changes where already done immediately).

I would just say edit settings in 1 window at the same time, while only 1 window is open.

But with a simple registry search for Explorer++ I personally found everything I needed so no problem remained.

Computer\HKEY_CLASSES_ROOT\Folder\shell\openinexplorer++\command tells you where the application was when installed it as the default. It has to be still located and launched from there in order to fix it.

In Computer\HKEY_CURRENT_USER\Software\Explorer++\Settings the property ReplaceExplorerMode is set to 3 when I have enabled it as the default explorer for "all folders" and 2 when I chose to set it for "filesystem folders" only, 1 means it's disabled.
It's probably set to 1 for you and that's the problem. Changing it back to the right value, and then properly disabling it in Explorer++ (after restarting it of course), resets everything.
