Thank you. So doing that, should I keep IE 10 or download IE 11 and do that? And should I activate all of the tools?
I would encourage you to upgrade from 10 to 11. IE 11 has a number of useful improvements over earlier versions.
One in particular is that 11 deprecates the old RC4 cipher suite for encryption. This is a critical security plus.
11 is said to perform faster than 10, even faster in some instances than Firefox or Chrome. I can't personally vouch for that, but only because I don't use IE enough to give a fair speed rating to it. It's also alleged to have a smaller memory footprint which is handy in a system with only a few GB of RAM.
I can't advise about the tools, since I don't use them. But if you would use them, I'd say it's worth a try at least.
Sorry I can't be more strongly pro/con but I want to be fair and my own experience with IE is only a tiny sample.
The most important one is the ActiveX control. If you disable it, you can individually authorize sites to run it if you want to watch some Flash.
I use Firefox as my main browser, but I have it so locked down on scripts (NoScript, Ghostery, etc) that I use IE 11 if I want to go to a poorly written site and not have to adjust all of the settings. Haven’t had any problems with 11 for those limited uses.
