See how others deal with this.
I recently upgraded to a new Dell Inspiron 530S with Vista Home Premium. For several weeks I have been getting this message almost every time I open a web page, click on a link or change applications:
?Microsoft windows search indexer stopped working and was closed.
A problem caused the application to stop working correctly. Windows
will notify you if a solution is available.?
Can anyone tell me what the search indexer is and why it stopped working?
Thanks NormG
