Widows Update creating havoc

Gday all.

Windows 7 recently did an update the other night on my laptop, nothing unusual there, but when I went to work on a project the next day, there was an amazing amount of drop outs and the error: “recording stopped audio drop out detected”. Bloody annoying, never had that before. Anyway, the only thing I could think of that had changed was the new update. So I unistalled the security roll out for Windows and the problem went away.
Just interested if anyone knows why this update could cause this issue and should I never let Windows do this update?

Cheers for reading.
