That's what I would do to. Or boot to a Windows98 floppy (God love those things!) and move the document files to another area. A reinstall WILL destroy the Windows directory and all its subs, but nothing else. Or you could get fancy and boot to DOS with TCP/IP support and map a drive to another machine and move them there. You'd have use the NET USE command.
I think it is bad luck to be superstitious
