it sure is. though i always take a look at all available updates one by one and then eliminate the needles ones.
Don't know about the rest, but WSUS failed on me: https://www.wilderssecurity.com/showpost.php?p=2289678&postcount=18
The only updates I usually exclude from updates are Silverlight and Bing Desktop As for security updates, fixes and some drivers, I just let it install.
i've seen on wilders some say silverlight and bing (and similar needles updates) keep showing up in updates even though they previously chose to hide them for future updates.
Install every updates, minus "silverlight", but I always have a fresh backup image before installing from Windows update, just in case....
is there a thread about microsoft updates? in short a list and release dates for vista,7 and w8 would be nice have a thread about it
