Helping people with computers... one answer at a time.

Cidaemon is the "Content Indexing Daemon", which is a background process that builds a fast search index of the files on your computer.

What is cidaemon?

That's the "Content Indexing Daemon"; a background process that builds a fast search index of the files on your computer. Chances are you don't need it, and can disable the indexing service. "Black Viper" has a good overview of XP Services.

After "retiring" in 2001, Leo started Ask Leo! in 2003 as a place for answers to common computer and technical questions. More about Leo.

cidaemon.exe, along with Indexing Services make the difference in Windows 2000 on minimalist hardware between just able to run Windows and having and enjoyable computing experience. It's never advisable to simple turn off anything Windows developers include with your system without first finding out why the problem exists and how to repair it. There is a "hotfix" available for this issue from Microsoft support. My advice is to download it and continue to use Indexing. If maintaining Windows takes too much of your time or unduly frustrates you how about trying Linux? Ubuntu now endorsed by IBM INVENTOR of the Personal Computer!

All hail Leo! I've been looking for a solution to cideamon.exe running all the time for weeks. Why couldn't I just have found Leo the first search??? Good to have my puter back on track. Thanks loads.

Great! This stopped cidaemon.exe from running automatically. I think there was a conflict between it and Google Desktop that was slowing my machine down significantly. Processing faster now though.
