I even had problems with signing out or putting my old man in sleep, because of the tedious useless process for singing in. My windows 10 went wrong several times after restart or shutdown so that it was not able to start again falling in a process of “starting” for eternity. I faced some difficulties after upgrading my Dell E6400 from Windows 7 to 10 (using free upgrade by Microsoft). Btw i have an Acer Aspire AMD Athlon(but says e machine at start up) if that helps at all…Thank you so much for your help.your site is the ONLY site that made any sense!! But the only option is to sign out and sign in, i do this several times, and the only thing that works is to shut down and reboot.not restart because restart does not work, i have to totally shut down and turn my pc back on.Do you maybe know why this is happening? And what i can do to fix it? I followed all your steps above.so im not sure what i did wrong. I’ll get a critical error message in a green box that says: Start up menu and Cortana are not working, we will fix this for you upon next sign in, or something like that. Its not like i have to have Cortana, but i cant get to my main screen without it.

i am successfully using the Windows 10 operating system.but, (there’s always a but, lol) sometimes my start menu and Cortana doesn’t work. I have the GeForce 6100 n Force 405 display.after i followed your directions step by step, and used the 64 bit downloads. I had Windows 7 and was also getting the error message for my NVIDIA system.
