If you upgraded from an activated copy of Windows 7 Pro to Windows 10 Pro then you should keep the digital license. Are you sure that you had a digital license for Windows 10 Pro? I'm asking because Windows says that it doesn't have one and we can see the KMS setup key (T83GX), which suggests that you might of been using KMS the entire time.
He upgraded using a multiple edition iso but because the system has a MSDM for Home, the upgrade wasn't to Pro but to Home and he got a DL for Home, as you can see.
It's been a while since I've done it, but I don't think it's possible to upgrade from an activated copy of Windows 7 Pro to Windows 10 Home. Last time I checked you'll only run into the MSDM issue if you're performing a clean install. The OP seems to be doing upgrades though?
In my experience, the MSDM is leading, whatever windows is upgraded from. EI.CFG not always working anymore, PID.TXT does. Only the 10240 ISO can't read/use the MSDM, introduced with the release of 10586 aka 1511.
@Daz Thank you for all the replies. I installed Daz Loader and it did its thing and then I upgraded to Lower build of Windows 10. I had an old ISO with me. It was activated till that part. Then, I got the old creators update and upgraded to that part and then it started saying my Licenses was not activated. I am going to reinstall the whole thing again from Windows 7 again. Btw Thank you for the loader. I have been using the Loader when I had no access to the internet and I was just a kid back then around 2009/10 (I was 9 years old lol). They used to sell the pirated bootable DVDs of windows 7 with your loader in it. Back then Internet was something that not everyone had access to. Just owning a computer was a luxury. @Enthousiast Thank you for all your help too. I didn't understand the PID.TXT thing. Should I upgrade from windows 7 to windows 10 latest build.

Pid.txt is basically a text file with a windows key written in it.According to @Enthousiast your system already has a win 10 home key embedded in system bios(aka MSDM) so whenever you do any upgrade/clean install,this bios home key will take priority & force installer to select this key resulting in activation issue.The older version win 10 that you were using does not take into account this bios embedded key hence there were no issues. Using pid.txt you can force win 10 iso/installer to give preference to that key over your MSDM key.Just create pid.txt file in notepad with win 10 pro generic key mentioned above by @Daz (make sure show file extension is enabled to confirm it is pid.txt & not pid.txt.txt) & place it in "sources" folder of win 10 iso.
@whitestar_999 Tthank you... I understand it now. Is there a guide that I can follow for using pid.txt?
No guide required,just open notepad,type win 10 key mentioned above & then save it as pid(assuming your pc has default hide file extension setting aka you see a text file without .txt extension in your pc) so that its complete name will look like pid.txt Now open your win 10 iso & copy all its contents to a new folder(say win10 iso folder) on your hdd.Then copy paste the pid.txt you created earlier into sources folder of win 10 iso folder.After that just run the setup.exe within win10 iso folder & this time it should pick the pid.txt key & not your MSDM key.
