Associations for .doc, .xls, and a slew of other Office docs are now set to OpenOffice.
They should be set to the default (eg: immediate post-install of MS Office) associations.
The only fix I've got at the moment is to go through the file associations dialog one filetype at a time through MS Windows Explorer. Tedium doesn't even begin to describe this. "Open", "New", "Print", "Print to", ....
I know these are keyed to Registry settings somewhere, ideal would be to know the hive and values. I should be able to clone these from another system.
