If you click on the start button you will see "Search programs and files". If I enter a term for a known file such as "jaypao.txt" I get search results "No items match your search".
Somewhere I read that I might try to improve the search by going to the control panel indexing options, and rebuild the search index. I go to the panel and it shows "0 items indexed Indexing in progress". I click pause as nothing is happening, and close. I have no search facility - very inconvenient.
