I just installed Windows 8(64-bit), I had minimum problems, but when I went to Internet Explorer from the start page, with the tiles, and go to youtube.com it says it doesn't have flash. I installed both 32-bit and 64-bit versions for both IE and other browsers,
but it still does not have flash capability. Fortunately, if I go to youtube.com from the Internet Explorer you access from the desktop interface, flash works.
