Microsoft re-released on Tuesday (13/11/2018) the latest Feature update to Windows 10 version 1809, known as "Windows 10 October 2018 Update".

When the installation of Windows 10 v1809 update failed, the users faces one of the following symptoms on their systems:
Symptom No1: During the installation of the  Feature Update to Windows 10 v1809, the system freezes or stuck at Windows Logo and the only method to get the PC back, is to force shutdown the machine using the Power switch.
