The worst thing I have ever seen from helping elderly with their computers is the freaking AOL Desktop launcher. I don't know how or why it ends up on their computers, but it's an overlay that makes everything look like Windows 95 and it's slower than crap. https://get.aol.com/aol-desktop-goldYeah, it looks like shit. But if someone wants their computer to look like shit for $5 bucks, it's their computer. They can do what they want.
I see no reason to side-grade at this time.1% of all Computers have been upgraded only. It has been nothing but a smooth ride for me after the 1st month that is after using the Start All Back taskbar program.
