Stupid error why i can’t update my window 10 error code 0xc1900204

After countless time restart my laptop for updating but my laptop said it failed to update because no error code. I had google many time to figure out the reason but i can’t find. One day, I tried with Japanese keyword “windows 10、バージョン 1703 失敗”  and luckily i found


It show me error code “0xc1900204” and from it i found my stupid mistake is that i had changed the registry Value.  I remember why i changed the registry Value, cause is my window drive C: \ is SSD drive and limited 500 GB so i want to automatic change new software install folder to normal Hard Disk drive D:\. That is where my trouble come from.
