I would just be only concerned about the security updates Lisa.
Don't know about the others..i also didn't upgrade to IE8, my computer started acting up, when i downloaded it..so i took it out.
i just got a call from my computer guy, and even though he reformatted the drive,he has to do a "boot and nuke" on it..(special program) it makes me sick. that people have nothing better to do, than to make trojans and virus programs..
my son in law works on computers in the school district, and some virus has him up in arms.
make sure you have a back up, in case of a virus..( a seperate hard drive.) it is just not worth the anger and frustration. and then at least you will have all your documents,pictures and favorites or bookmarks...
