If you go with explorer to adobe get flash it links to old version still...
Seems also win 8 (IE10+) got an update from microsoft today:
https://support.microsoft.com/en-us/kb/3065823
But it requires an OPTIONAL update to be installed first, so should go in windows update, go show the optional ones, install them, and only after this, may update the flash thing?... I would have put all mandatory, no?
So what you have to do is to to windows update, show "optional updates", select them and install, it reboots. Then re run windows update and only then, will show 2 important updates, one of which is 3065823 which fixes flash.
