Hello again Neon.
Did all that....icons were fine.....til I rebooted then back to unknown file icon.
I have found that icons are here;
C:\WINDOWS\Installer\{90280409-6000-11D3-8CFE-0050048383C9}\wordicon.exe
However this seems to get deleted each time I reboot and replaced each time I use one of the repair tools

??
Regards,
johnno
