I know what uphclean is but in the second error the path
driver:WINIO;file:C:\WINDOWS\TEMP\WinIo.sys is not in my Windows\Temp
I can't find winio.sys anywhere with a search. (Yes I have folder options view to show all files etc)

Home Edition XP SP2

Any ideas how to resolve that error?

 

Thanks Pete.
