ignore the warning , custom domain don't support https , just save and wait for some time

back to settings , basic, once blogger is ready to enable this function , select yes in https availability and https redirect , save settings 

wait for some time when blogger to generate ssl certificate from let's encrypt , the free ssl certificate and https blog , it's done

windows server 2012 r2 kb4057903 issue and workaround

on january of 2018 , kb4057903 was released from microsoft , it is for windows server 2012r2 virtual machine guest os

if exchange 2013 or exchange 2016 was installed on windows server 2012 r2 virtual machine guest os , and try to install kb4057903 , there will be an issue
installation of kb4057903 will be fail , and when windows update ask to restart , system won't be start , and get stuck in "preparing to configure windows , do not trun off computer" screen for a long long time
when virtual machine guest os is ready to login , virtual netwrok is fail to load , there will be no any network connection

the only workaround is login into virtual machine
send control + alt + delete function key to virtual machine
start task manager
start new task from menu
type msconfig to start system configuration
on boot tab , select safe boot and click ok to reboot virtual machine guest os to safe mode

on safe mode , login with administrator account
from administrative tools menu , find services and catch screen shot for exchange services , so i know which services should start on system boot
scroll down to find msexchange service and disable all exchange service
execute msconfig command to start system configuration again , on boot tab , unckeck safe boot , and click ok to reboot virtual machine

login into virtual machine , try to install kb4057903 again , reboot virtual machine
virtual network connection should working well
from administrative tools menu , find services
check screen shot i just got and restore all exchange services state
reboot virtual machine , every thing should be working well
