How to upgrade Win 7 32 bit to Win 10 64 Bit for Free after 29 July 2016?

How to upgrade Windows 7 32 bit to Windows 10 64 Bit for Free after 29 July 2016?

Problems:

    - Free Win10 upgrade is actually closed

    - 32 Bit to 64 Bit is never a provided upgrade function from Microsoft

    - If you don t want to upgrade to 64 bit - just use the Microsoft page for "assistive technologies", which still 

      provides the FREE upgrade to Win10

      https://www.microsoft.com/en-us/accessibility/windows10upgrade

Solution:

-   Have a  (min) 4 GB USB stick ready

-   Download Product Key Viewer and write down product key:    
     http://www.chip.de/downloads/Windows-Product-Key-Viewer_58663752.html

-   Download ISO file to HD (function "bootable USB" will not work):
    https://www.microsoft.com/en-us/software-download/windows10/

-   Download old "bootable USB from ISO" tool from Microsoft:      
    https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool#installation

-   Run this tool and select ISO from HD to create bootable USB stick

-   Reboot PC which you will update and press F2 for Bios setup

-   Goto Boot Setup and move USB to first position

-   Plug prepared USB stick and save / reboot

-   Enter Key from Key Viewer

-   keep going and select "Custom Setup" (everything will be deleted)

-   Chose Keyboard / Language

-   Windows will start setup and count up from 0% to 100%

-   IMPORTANT: when on 100% remove USB stick before Windows is rebooting -
    otherwise installation will loop  ;-)

-   Keep going with the rest of the set-up (which is very easy and straight forward)

-   ENJOY
