The unique way to solve definitively the problem.
In Regedit delete this two registry keys:
Value "ModernViewStatePersist" in
"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
Value "ModernViewStatePersistent" in
"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
Delete also the folder below:
"HKEYCURRENT USER\Software\Microsoft\Windows\CurrentVersion\
Explorer\CLSID\{949ECF34-5756-4b9c-9692-2decAA8b91a2}
Don't update the data with Amiquote, because is through it that they modify the registry.
Now AmiBroker dont go nevermore to unregistered.
