Well, thanks, I think. I went to the link, and the screenshots posted there do not look anything like what I am seeing by typing "index" into the Start search box and then indexing options. I see a typical XP style box with a large white window with headings of "Included locations" and "exclude" on a delimited style slider bar. Below that are three buttons, two active, one greyed out. The active ones are "modify" and "advanced". The greyed out one is "Pause". Clicking on either of them brings up nothing remotely like what the link describes.
And yes this is Windows 7 on here!
