I'm running W10 v1803 (upgraded from Windows 7) on a 5 year old Toshiba laptop and I keep getting reminders that this version will not be supported after November. But when I've tried to update (used both the Troubleshooter and Update Assistant), after a lengthy process I get the message "Windows could not install one or more system components. To install Windows, restart the computer, and then restart the installation". Of course, that does nothing but repeat the error message. I am not a skilled user but would appreciate any suggestions that might make this work.
