More to try:
Control Panel\All Control Panel Items\Default Programs\Set Associations
Set .doc to open with some other application and apply. Then re-associate it with word and apply.
Regarding rebuild icon cache script. Did you wait for the message prompting you to reboot when you ran the script? It can take a while to appear so it's easy to close the command window before you see the prompt.
Also do you have any registry backups that were created by any third party software recently. Search your HD for .reg files.
In SwiftSearch *backup*?.reg returns results for file names containing the word backup with the .reg extension. I'm not sure if the same works in Windows Search as I don't use it and it's disabled.
If you have such a backup try imaging your current drive then restore the backup.
Thank you for all the suggestions but me being me I got frustrated, backed up what I needed and stuck in a ghost image from a few months back. All is back and good. Sorry for wasting your time.
