Windows 10: Unable to upgrade from Windows 10 1803 to 1809 using Update Assistant

I am trying to upgrade build 17134.441 to 1809 using the Update Assistant. The downloading and installing goes fine, then I get the restart countdown of 30 minutes during which I restart and then I get a screen saying, upgrade 'Your PC will restart several times.'

It all looks fine till here, but as soon as the progress reaches to 15% on this screen, the system reboots once, I see the bootloader logo and then after about 5-10 seconds the system reboots again.

At this time, I see Undoing changes made to your computer and I'm back on the 1803. I have tried clearing the update assistant cache, my updates are working fine because I keep getting cumulative updates for 1803 from the Updates in settings, I tried upgrading from 1803 to 1809 several times and I always see this happening at 15% progress.

Any help would be greatly appreciated.

Win 10 1803 to 1809 update

Good day one and all.

My Desktop computer running Win 10 updated from version 1803 to 1809 a while back, but my laptop/notebook running Win 10 version 1803 (As of a Check for updates today 15 Nov 2018 6:30 AM) still hasn't updated to 1809.

I'm assuming the update 1803 to 1809 has now resumed after the earlier problems caused a suspension?

Updates in general on the laptop are coming through as available, for example, yesterday (14th Nov 2018) the "Cumulative Update for Windows 10 version 1803 for x64 based Systems (KB4467702)" arrived and was installed okay.

Any thoughts, suggestions?

Thanks

Arturo

Windows 10 upgrade assistant stuck at 99%

The problem is caused by the Windows 7 updates.

Before using the Windows 10 Upgrade Assistant, perform these steps:

• set Windows 7 updates to "Never install updates".
  
• Stop the update service by right clicking on the command prompt, and choose "Run as administrator".
  
• Type
  
  
  It should say: "Windows update service is stopping....windows update service is stopped."
  
  
  
  

After completing the above steps, start the Windows 10 Upgrade assistant, and it should complete.
