There are some bits I disable:
windows Media player sharing
wireless config
homegroup crap
,...............
And: lots of stuff is now started from the task scheduler:
defrag
windows update
hardware performance analysis,...
MS user happiness services and reporting,....
What annoys me the most is not being able to disable/schedule the AV update time.
Very stupid.
Not networked is good for general use. And if your area is lightning prone: another way for electric jolts and crap to get into the computer. And the constant poling.
But: connecting for updates and the online reference manuals,... Is good.
I currently am using only the windows defender for AV.. I do not surf. But I do often have the CW forum open for learning.
And now with the "free" videos I will have a browser open to view such.
Sometimes I do use a netbook for this stuff when using sonar.
