Thanks for this.
I have checked the HP website and any machines pre 2013 are not supported by HP for Windows 10.
My wife's HP laptop is the same age and it updated to Creators with no problems at all.
I have tried all suggestions from the internet including disabling my AV (Norton), disconnecting all periperal devices and disconnecting ethernet and wifi before trying to install.
I have been trying to install the Creators Update for weeks now and it fails to install every time.
Within seconds of clicking 'Restart' after downloading, the attached message appears and the installation fails.
What does this message mean?
