Flash Player & Windows 8

I can't even bring myself to "sugar coat" this anymore.

STOP using Internet Exploder. Period.

It's the worst browser there is. Just because Microsoft includes it with Windows, doesn't mean it's the only thing you can use to surf the web. Unless you're using a company computer and restricted from using anything else, it's senseless to torture yourself with IE.

Chrome (free from Google) isn't much better. While it works where IE doesn't, it's a major resource hog. It's the most used browser out there, but that's because of all the Android phones that have it. Besides, a lot of people do;t like it because sftware  companies "bundle" it with their downloads and updates - Adobe included.
Safari (free from Apple) is a good, safe, fast browser with plenty of features and customizable with extensions.
Opera (also free) is more of a "bare bones" interface, but it's customizable too, and faster, safer & more reliable than IE.

Firefox (free... and the browser I use) is fast, safe, customizable, and has tons of extensions for things like blocking annoying ads.

For any of these (except Chrome - which has it's own plugin, like IE in Windows 8) you'll need the Flash Player Plug-in (For all other browsers) but you'll be able to get to Flash pages that can't or don't recognize IE11, anf you won't be annoyed by constant "Are you sure you want to run this...?" warnings from IE's ActiveX controls.
