I am having Dell Inspiron N-5010 Laptop 64-bit architecture, and I have installed windows 10 Version 10586 32-bit side-by Ubuntu 16.04 64-bit. I want to upgrade windows 10 version 10586 to version 14393. Every time if i check for updates from settings, it starts to downloads the updates and ask to restart after downloading finished and after restarting no changes had happened. I have checked with my desktop which is having the same windows version (without ubuntu) for the same updates and there is no issue with it. So I used "Windows 10 Update Assistant".
But it didn't help me, So how to solve this issue?
and i have seen this ".esd" file in the time of the updating progress in one of the local disk. Do i have to use that file in any of the way?
