    2# Delete everything in this Directory, (files within side the Download Folder) Not the download folder itself. This will cause you even more issues.

    3# Open up a command prompt and run it as admin. To do this type Command in your search bar as below, then right click and run as administrator.

    Here we need to create a new DWord(32 bit) with a name of AllowOSUpgrade and a value of 1. Simply right click> New DWord(32 bit)

    Once your Dword is created, double click on it, this will allow us to change the value to 1 like below:

    Hit OK

    That should be it, restart your machine and see it it allows you to update...
