Stuck on "Setting up personalized settings"

[acid8]

Hi,

I have recently had my laptop restored to factory defaults from Sony after the hardrive failed

but now when I try to update to Windows 8.1 as soon as I log in it is stuck on a black screen with a pop up box in the top left corner saying

Setting up personilzed settings

C:\Windows\SysWOW64\Rundll32.exe
C:\Windows\SysWOW64\mscories.dll.Install

All I can do is use ctrl + alt +delete to manually start programs using New task in Task Manager or shut down etc

I've resorted to resetting pc back to factory defaults to start again

Any ideas?
