Ciao a tutti.
Da poche ore mi ritrovo lo scroll del touchpad bloccato . Ho un portatile Samsung R530.
Ho provato la chiave di sblocco Fn- F12 ma non è cambiato nulla.... Aiuto!

Ho Momentaneamente risolto ma ho dovuto ripristinare il sistema a 4 giorni fa, cioè prima che venissero fatti gli ultimi 15 aggiornamenti Windows. Ora però mi tocca scoprire quale è l'aggiornamento incriminato. Come Faccio? :-(

Ciao luke! Quando ti verranno proposti, installa uno o due aggiornamenti al massimo per volta e verifica.

Per postare le immagini, leggi qui.

Grazie amici miei :-) Ho risolto installando tutti gli aggiornamenti di Windows tranne i sette aggiornamenti di Microsoft.Net.Framework che tra l'altro sono stati rilasciati tutti contemporaneamente. Tra questi c'è pure la versione 4.5.1 per Windows 7. Posso vivere anche senza questi aggiornamenti o sono essenziali?
Inoltre ho notato che aggiornando da Explore10 a Explorer 11, ho dei problemi su youtube. Posso tenere Explorer 10 senza rischiare per la sicurezza?
Grazie ancora :-) :-) :-)
