thank you very much for your question. My name is***** and I will try to help you as quick possible.
Am I assuming right that you are trying to update to Windows 10 from an older Windows (7 or 8 or 8.1) and that the update to Windows 10 is failing? If so, I would recommend that I take a look at this directly at your computer, via a remote-assistance and fix it for you, so that you can install Windows 10. I am making you an offer for this and if you are interested and have accepted it, I will give you instructions on how to start the assistance.
Thanks for your patience and best regards,
I see that you´ve read my reply, can you please let me know how we should go on? I would really like to help you so that you can upgrade to Windows 10.
Thank you very much and best regards,
