I am upgrading a computer from Windows 7 to Windows 10. I completed the download, and got a message that the computer needed to restart to continue the installation. However, when I restart and the computer comes back up, the same message appears and the installation does not progress. When I go to check Windows updates in the control panel, it says it can't check for updates because another installation is in progress. I have restarted the machine multiple times with no progress - can't go forward, can't go back. Has anyone found a fix for this issue?
