    Win10: windows update stuck at never ending loop ?

    When in win10:
    • Update&security -> Windows update -> Finding update... .... .... ....
    Planning to download the latest Win10.ISO (vers.1803) and manually update:
    - Then wait that my ordered new SSD arrives and clone the old HDD to it.
