I was upgrading from Windows 7, the only version ever to run on my 4-year-old HP Touch-Smart desktop PC. I had never installed Windows 8 because of all the bad press it had gotten. The Windows 10 upgrade went smoothly and took about 90 minutes. It's loaded with features, most of which I have no use for and disabled during the upgrade.The familiar Explorer still looks the same, and all my folders and files remained in the same order as before.
I haven't run into any serious problems, but I've encountered a few bugs of the annoying variety, and I just don't like some of the changes to system settings. Screen background doesn't seem to work properly, I can't figure out how to enable sounds for program events, the start menu sometimes fails to open and I have to restart Windows to recover it, and my administrator login has disappeared.
Internet Explorer has been replaced by Internet Edge. I transferred my bookmarks from Firefox, but now when I click on Bookmarks in Edge, it causes Edge to close, so I can't use bookmarks, severely limiting Edge's usefulness. But it doesn't matter. I had planned to stick with Firefox anyway. All my applications work as before, no problem with internet or email access, and I can network with my Macbook Pro as I always have.
Overall, I can't find much reason to recommend Windows 10. I can't comment on Windows 8 because I've never used it, but if you're running Windows 7 with no problems, I suggest sticking with it. Windows 10 is no improvement over 7, or Vista for that matter, at least for my purposes.
