I have a problem while activating Windows 10 Home on my wife’s desktop.
I have two keys, one is Windows 8.1 Home Single Language UEFI key which was preinstalled with my PC. I have upgraded it to Windows 10 while it was free.
The other one is Windows 7 Home Premium key I took it from my old laptop (it was broken and I threw away, also I didn’t upgrade that to Windows 10 while it was free).
I managed to activate Windows 7 Home Premium key on my wife’s desktop after I installed Windows 7 on it. There was no problem until I realized something. When I install Windows 10, it activates itself automatically and says “Edition: Windows 10 Home Single Language” and “Windows is activated” in Settings>Update & Security>Activation tab. Then I enter Windows 7 key and it activates itself again and says “Edition: Windows 10 Home” and “Windows is activated” in Settings>Update & Security>Activation tab.
But when I check the PC’s product key from the “ShowKeyPlus” program, it shows the installed key as 37GNV-YCQVD-38XP9-T848R-***** and NTRHT-XTHTG-GBWCG-4MTMP-***** for each edition in Windows. Also, I run slmgr /dli in cmd, it says it’s on OEM_DM channel for both activations (Partial Product Key: FC2** and HH6** for each).
After these problems, I tried to activate Windows from cmd. I tried the slmgr /ipk command with 8.1 and 7 product keys, but I got different errors for them.
Windows 8.1 key=> Error: 0xC004E016, Software license service reported that the product key is invalid.
Windows 7 key=> Error: 0xc004f050, Software license service reported that the product key is invalid.
What to do about this issue?
