Windows 10 update error 0x80242006
on Windows

Hi. I installed the Windows 10 v1803 but decided to roll back to the previous built because of some problems with the new Start Menu, the tiles, and Windows Store. It seemed to me that the update was rolled back successfully to 1709, but then when I tried to update Synaptics mouse driver via Windows Update, I came up with an error saying: "Feature update to Windows 10, version 1803 - Error 0x80242006."
