I am running Win 7 with Parallels 9 with no hassles. But I do have a copy of Win 8 which I am tempted to install (and then upgrade to Win 8.1) I do not have a reason to upgrade to Win 8 other than to be running the latest and hopefully more secure version of Windows. So my question to the group is: Should I do it. And if I do any tips to make it go smoothly? Thanks Gang! Dunc
