You are correct, from Windows 8 onwards all Flash Player updates are pushed by Microsoft as part of Windows updates. Please go to Windows updates and see if any update is available for your machine. Additionally, please check on other pages like Adobe - Flash Player if you can view Flash Content without any issues. If you are not seeing any issues here please post a screenshot of the page where you are being prompted. It could be a case of phishing.
Hi so it turns out I was severely out of date and it took me a few says to update but I am still reading an error message anytime I try to play media that requires flash player. I have checked now that I am to date that every plausible setting regarding the flash player is turned on but it still refuses to play any media such as Hulu shows. I get a message saying "InvalidStateError" and sometimes a link to the adobe official site.
But thank you so much for your help!
