I was updating my laptop Windows 10 Home from 1803 to 1809 with the windows update assistant. The download process and install process were running pretty good. After installing, obviously the laptop will be restart to further the update. My laptop restart and went into a booting-like update screen with the percentage of update had done. the problem comes. It update until 17% and it restart and boot into my computer. I went into and check the OS build number and it still remand the same, which is the 1803 version. Can anyone help or explain what is going on. It kinda strange and i went through lot of forum still couldn't find out why. Can someone discuss bout it?
