I'm unable to perform the Windows 10 Feature Update 1803 update. The downloading process is stuck at 100% and after sometime it fails giving an error code 0x80240034. There's no problem with my Internet connectivity & speed. I'm currently running 64 bit OS Pro with build 17134.345. I have performed an Update troubleshoot with administrative privileges which found Potential Windows Update error detected. I presume this is in the update and only related to the update as wu10.diagcab reports this potential error and cures it by deleting update from my installation. When this eventually gets downloaded it will not provide a restart and install updates button and there seems no way to trigger the update to start.
