Do it before going to bed and leave it on.
I upgraded from Windows 7 to Windows 10. The software I use for work had some issues. The software issue has been corrected and I'd like to upgrade to Windows 10 again. However, when I click on the box that says, "Ok, let's continue" it goes to the window graphic with the text, "Working on it..." which times out and disappears with no further action. How do I overcome this issue to upgrade to Windows 10 again?
