RE: Window 7 genuine while upgrade to Window 10 than it becomes pirated

Power off your Dell. Remove the AC adapter and Remove the battery. Your Windows 7 COA should be present there. Use your phone and take a picture of the COA. Then replace the battery, AC adapter and power the system on. Try to activate Windows 10 TH2 using the Windows 7 OEM Product Key.
