Angels have the Phone Box
Well, that may be the best for your system at the moment. I understand that some programs, like Chrome browser x64 doesn't play nice with W10 right now, although the 32bit does. Also, major enhancements are due out some time in October for Edge, including extension support. Perhaps you could try it again later.
Please mark the thread "solved" in the upper-left for now. When you decide to try it again, perhaps post a new thread for advice of how to prepare your W8.1 for upgrade, in case there are known bugs at the time. People here will give you valuable advice, and even check your particular system specs and installed programs, to look for possible snags.
