Ciao a tutti.
Appena dopo avere scaricato Explorer 11 per Windows 7 sto avendo dei problemi con Youtube. La pagina iniziale si blocca e Explorer cerca di recuperarla ma il problema non si risolve. Riesco ad utilizzare la pagina solo dopo vari recuperi.
Da cosa può dipendere?Grazie infinite.

Ecco una pagina web su cui molti si lamentano dello stesso problema.
http://servizioallerta.it/problemi/youtube

Non uso IE ma ho fatto una prova e le difficoltà ci sono spesso si blocca e solo dopo il ricaricamento della pagina funziona.
Gli ultimi aggiornamenti hanno creato diversi problemi speriamo che li risolvano al più presto.

Niente da fare. La pagina Youtube non risponde, mi chiede di ricaricare pagina, ma sono costretto a ricaricare molte volte pria che la pagina sia fruibile.
Ma se provassi a disinstallare l'aggiornamento "Explorer 11" per Windows 7? Il problema è nato dopo l'aggiornamento

Problema risolto disinstallando l'aggiornamento Explorer 11 e tornando a Explorer 10. Adesso però Explorer 11 mi appare tra gli aggiornamenti facoltativi , mentre prima era fra quelli importanti. Perché?
Inoltre ho notato che da quando l'ho disinstallato Windows non mi segnala più aggiornamenti disponibili. L'altra volta ho provato a cercarli manualmente e ne ho trovato uno di Windows defender. Come mai?
