Upgraded Windows 7 to Windows 10. Worked fine on test PC so tried on production PC. Test and production PCs are both DELL and test PC 2 years older than production.
Production PC, after login (login screen is fine) results in black screen with operational cursor.
Can only execute commands from Task Manager | FILE | Run New task.
Cannot access SETTINGS menu to roll back.
Any way to accomplish via DOS commands or other method?
