Hello Abdul,
Welcome to Microsoft Community.
After fully reading the thread you posted, I'm not quite sure why you posted this issue in the Surface Duo section, as your issue seems to have nothing to do with the Surface Duo's power supply and battery.
At first, I speculated that you might have a need to merge accounts. However, after some searching, I surmised that the problem you are referring to here is not the consolidation of Microsoft accounts, but perhaps two MC IDs:
Merge MCID - Training, Certification, and Program Support
Because for an individual user, you don't usually have a name in a format like MS000000. So please refer to the above link to see if the information is what you need. If correct, you can also post your question here, which should be the most appropriate section for your question:
Results in Microsoft Credentials - Training, Certification, and Program Support
Best Regards,
