L'errore riportato nel titolo è quanto ci viene segnalato quando cerchiamo di fare un punto di ripristino in windows 7.
Per ovviare a questo inconveniente dobbiamo agire su un servizio del sistema operativo:
1) Click destro su Computer/Gestione /Servizi
2)Click su SERVIZI e nella finestra cercare REGISTRI EVENTI DI WINDOWS
3)Doppio click e nel menu a discesa mettere questo servizio in AUTOMATICO/APPLICA/OK
4)Riavviare la macchina
***********************************************************
Una seconda metodica, se la prima non funziona: copia incollare quanto racchiuso fra le due linee tratteggiate nel NOTEPAD e poi salvare con un nome a piacere ed estensione *.REG.
Lanciare questo file e confermare la sua immissione nel REGISTRY 5.
