Inside CClean there is
Registry Icon when you click on that
Scan for issues when you click on that
It will sacn and then you will see Fix Selected Issues
When you click on that
Do you want to back up changes to Registry
If you choose YES one of the choices is DeskTop
I saved to DeskTop
a few days later when all seemed to be working I decided I didn't need the Registry that was saved any more and I clicked on it to Select and then Delete. Well the OLD registry setting Loaded.
DeskTop should NOT be a choice as a place to Save Registy
