Nessuno sa dirmi a cosa sia dovuto questo warning che trovo con tanto di triangolo giallo con punto esclamativo nel log degli errori?

Windows saved user *****\*****registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.
