Flash Player for IE in Windows 8 and 8.1 is embedded by Microsoft, and without removing several unique registry keys, and one specific Windows Update KB Patch, it cannot be uninstalled.
I seriously doubt you, or anything on your system, did all that, so it IS still installed.
If you're one of the unlucky souls who updated to IE11, your problems stem from the browser, NOT the Flash Player plugin.
Microsoft really did a number on the code for IE11, and pages can't recognize the browser, so they don't recognize any of the plugins, like Flash Player. So far, Microsoft has made NO indication that they have any plan to fix it soon.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using an different browser. Trouble with that is it has seen limited success at best, and you have to individually enable it for EVERY page that has problems.
I'm not big on "pretending" so I recommend actually using another browser.
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.
I dont know much about it but my screen went green when watching videos and my friend said he was going to uninstall it and reinstall it i know he uninstalled it i dont know if he fully did or not but when it serches for it on the website it says it is not installed idk all this stuff confusses me
thank you for your help though I appreciate you trying to help
"Green screen" IS NOT caused by Flash Player... (Tell your friend NOT to help anymore)
Green screen is 99.999% of the time due to outdated or corrupted video drivers.
Update them from the manufacturer (NOT Windows): http://forums.adobe.com/thread/945765
