I restarted my laptop today to update Windows 10 and there are now many changes to my system (I upgraded to Windows 10 from Windows 7 in October). The first things noticed were that my desktop wallpaper was changed to the default Windows 10 wallpaper and all of my desktop icons are gone. All of my taskbar customizations are gone. I imagine this is what the default settings would be if one does a clean install of Windows 10. I cannot connect via wireless. Right clicking on the Wi-Fi connection in Network Connections and selecting Diagnose gives Problems found The Windows wireless service is not running on this computer. I selected Try these repairs as an administrator, but this did not work. I looked into doing a system restore and found that there were no restore points available and restore monitoring was turned off. I had made many restore points previous to today. In View Your Update History in the advanced options for Windows update, it tells me I have no updates installed yet. Windows has updated several times since I upgrades. After clicking uninstall updates I only find KB3116908 installed today. Neither Avira or Comodo are running. My apps are still in the Start menu but I have lost all the customizations I made to the Start panel (Calendar, News feed...) Appears those have gone to default. When opening Firefox I get the set as default browser messages as if I had never opened Firefox before. I have Firefox set to open with the previous session and it did not. It does not have any of my customizations either (bookmarks, add-ons...) It seems as if I have logged into Windows as a new user for the first time HOWEVER I logged in as usual with the username and password that I have always used. The one thing I have found that has remained unchanged is my picture next to my username on the Start menu. It sort of seems like a new user has been added with my credentials but I don't think that would explain why the Wi-Fi service is not running. I would greatly appreciate any assistance to get back to my settings without changing every single thing that has been changed. Thanks in advance!
