Simply run INSTALL.CMD again. When prompted for whether you wish to register or unregister XFolder, select "unregister".

Reboot, and everything will be as it was. You can then delete the XFolder directory, if you wish.

If you wish to remove XFolder because you don't consider it to be of any use for you, that's fine.

However, if you remove it because it does not seem to be working right or messes up your system, please contact me so I can improve it.
