I mentioned this before but it bears repeating. A friend works for microsoft. As soon as windows 10 was ready to release, he notified all of us not to install. If you purchase a new computer with 10 preinstalled, it will be fine. But ignore all those messages to upload to your existing computer. Windows 7 will still be supported for quite awhile and those of you who installed 8 have probably worked out all your bugs by now. Wait on 10. But, again, if you purchase a new computer with 10 preinstalled, you should not have any problems.
