Know of a good source of info on updates?

I've had it with updates screwing up my computer! Had to restore twice
in the last 4 days due to some update that is supposedly unobtrusive
(according to the sources I know of) causing a lock-up whenever the
computer was provided with access to the internet (WiFi or wired). No
malware detected by scanners, and no hardware problems. I've narrowed it
down to a handful of KB's, but no longer trust the info on them that
I've found, and of course, MS is pretty much useless in this regard.

Suggestions appreciated.
