Ciao a tutti.
Da oggi ho notato una Cpu molto alta a causa di scvhost.exe.
Potreste darmi uno sguardo al log di Hijackthis?
Grazie di cuore.

Ciao
Sono gli aggiornamenti purtroppo.....
Il responsabile è wuauclt.exe , lo vedi tra le prime righe .

Non c'è una vera e propria soluzione..
Devi aver pazienza e magari impostare gli update in maniera diversa da " aggiorna automaticamente

Esegui tutte e tre le opzioni.
Poi riavvia la macchina e riesegui wupdate.
Tieni presente che potrebbe volerci parecchio tempo prima che trovi aggiornamenti.

Ciao
Tradotto in parole povere:
Per ogni punto devi scaricare dal bottone blu download.
Salva sul desktop
Tasto DX sul file " eseguì come amm.re
Acconsentì con OK alla richiesta di eseguire il file.

Per i.e11 puoi cercare da google,
Sono fuori casa e i link Microsoft da android non sempre sono esatti
