You understand that Flash is integrated directly into IE in Win8+ but non existent in anything under, right? You’re freaking out over nothing dayglo.
Neither the Microsoft.com page, nor the Register article, mentioned Internet Explorer at all, or that would have reminded me that "Flash in Windows" really means "Flash in IE". And since I do not use, nor does my company support the use of, Internet Explorer, I've ignored (and largely lost track of) recent changes to IE. On my Windows 10 boxes I use Edge; on everything else I use Firefox, Chrome, or Opera.
So you're right, and my comment #3 at the top:
"Or perhaps someone with more time to research this can show me where the Flash vulnerabilities dont apply to Windows 7..."was more accurate than I thought.
Thank you!
