@Tibs....yeah, it takes some digging in to figure out what's going on.
I have a "Google News" link in my bookmark toolbar. I check it several times a day between stuff, but I don't usually leave the tab open. And I'm on cable internet. If I was really watching my usage, I wouldn't leave it open long at all and would make sure to close it. It auto-refreshes.
You may want to manually load updates every other day too. So it doesn't check all the time.
Also, flash player checks that every hour. Flash is the biggest pile of crap on the internet, nothing but a security hole and data hog, IMO. IDK if I remember the XP version...I know the win 8 version has a scheduled task that runs every hour to update flash. I usually have it set to run every day instead of every hour. I have to remember to go "fix" it after each update. For me in Win 8.1 is in the scheduled tasks. Finding and editing is a bit hard to explain...it's in the properties of the task.
Windows update only checks once per day so I'd leave that as is.
