Hello! I've found a working method that I experienced myself!
First off follow the instructions because this is how I did it myself.
1. Go to " Control panel "
2. Click on " Uninstall a program "
3. Search for " DeskFX "
4. Right click DeskFX & click on " Uninstall/Change "
5. Make sure that in this step that you have DeskFX Power Button ON and your Speaker / Headphones or whatever is Checked in the Options panel on DeskFX.
6. Now you will go to Control Panel and click on "Delete a program" in the many choices of applications in the Control Panel.
7. Search in one of the many apps for " DeskFX " and right click the program and press " Delete/Change "You will be prompt by a configuration window that will say either, Delete, Repair or 3rd option. Press " REPAIR ".
8. Now when you have done these simple steps you are good to go!
