I just installed Windows 10 pro and activated it successfully as per the the instructions on this site. I also installed Microsoft Office latest version. Later I realised what the shit Microsoft did with Onenote. I am not able to open previous version of Onenote files on new office. I only use Onenote in office package. And i saved my all files on Google Drive for future purpose if my laptop crash then I can access it on new laptop. Same thing happened. After I purchased new laptop and tried to open it, I was unable.
Now I am with my new laptop with windows pro activated but without access to my previous notes. Alas. What to do. Is there a solution other then searching an old working laptop with previous version of Office.
