Windows 8 no update pop-up's or voice notifications.

As the subject says. Is this normal for the windows 8 update?

I’ve got 4 computers here, 2 WinXP, 1 Win7 and 1 Win8

The XP’s and Win7 updates all went as planned. But since I updated avast on the windows 8 computer I’ve not heard any notification voices or the pop-ups that usually happen.

The XP’s and the Win7 update went as expected.

Anyone else seen this happen, and how is it solved?

P.S.

The only thing I’ve noticed since updating avast on the XP is the shut down time takes slightly longer. It does shut down but takes longer. Not sure why this is.

Have you checked to see if Gaming Mode has been turned on, that would stop the popups etc. ?
