Hi Ady72,

How did you do the upgrade? Have you created the recovery drive?
We can refer to the link as Milos posted to upgrade the Windows 8 system.

For your issue,we can try to run "dism /online /cleanup-image /restorehealth" to have a health check of the whole system files.

Please note that "If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, refreshing your PC will restore Windows 8. Youll need to upgrade to Windows 8.1 after the refresh has finished. "
Here is a link for reference of doing refresh
