In genere gestione attività Windows si apre con i tasti in simultanea Ctrl Alt Canc. Da qualche giorno invece il programma non si apre. Addirittura quando già premo Ctrl e Alt sento il suono di un bip sincrono con lo schacciare del tasto Alt. Non noto nient'altro di partioclare nel PC. E' sintomo di qualcosa?
Grazie

quando succede qualcosa d'imprevisto, io partirei sempre da una pulizia generale. spesso si sistema il tutto

Mi resta solo da deframmentare

I vari log non presentano problemi, fai una pulizia del registro con questo sw:

Per una pulizia profonda del registro, usa Eusing Free Registry Cleaner sw da usare saltuariamente, lo scarichi da qui: http://www.eusing.com/free_registry_cleaner/registry_cleaner.htm
clic su Download Site1, una volta lanciato appare una finestra che chiede il codice, clic su ignora e procedi, poi in alto a sinistra clic su Analizza Registro, lascia fare fino alla fine non ti preoccupare se trova molte voci, poi clicca su Ripara Registro, il sw è sicuro comunque crea un punto di ripristino e fa anche il backup dei file eliminati infatti in alto sotto ripara registro si trova la voce Ripristina Registro.
Per fare questa pulizia meglio chiudere tutti i programmi e disconnesso.
Il programma è compatibile con tutti i S.O. windows compreso win 10.
Gestione attività si apre anche facendo clic col tasto destro sulla barra delle applicazioniin in basso e cliccare su Avvia Gestione attività, molto semplice
