Try to install the important update.
Reboot and check Windows update again.

Thank you Peter - important update installed - 2 x optional remaining...

 

[PeterJ]

No need to install the optional update.
You can try the upgrade to Windows 10 again.
Make sure to have a backup of your important data first.

Ok Peter thank you - yes I did a full C:/ back up before I initially tried my 1st Windows 10 upgrade...

 

[MagicalMusicMan]

I am disconnecting the interent I am running mediacreation via a mounted ISO and ticking no to updates - is this correct Peter?

 

[PeterJ]

If the internet is disconnected the "Not right now" option is the only one then.

 

[MagicalMusicMan]

Thank you...

No joy Peter - sadly the Win10 upgrade failed once again - exactly the same as before 'Working on updates gets to 71%' Your device ran into a problem and two restarts before the same error comes up;
We couldn’t install Windows 10.
We’ve set your PC back to the way it was right before you started installing Windows 10.

FRST Scan:

1. Download the Farbar Recovery Scan Tool and save it to your Desktop:
   64-bit: Downloading Farbar Recovery Scan Tool
   
2. Right-click to run the tool as administrator. When the tool opens click Yes to disclaimer.
3. Note: Ensure that the Addition.txt check box is checked at the bottom of the form within the Optional Scan area.
4. Press the Scan button.
5. Please wait for the tool to finish. It will produce two logfiles called FRST.txt and Addition.txt in the same directory the tool is run from (which should be the desktop)
6. Post the logfiles FRST.txt and Addition.txt as attachment in your next reply.

Thanks for your recent help Peter; I will have to wait for another window to open before I commence with any upgrade solutions as I need my PC running for work deadlines - thks again

No problem. Take your time.
