Since I installed Vista, I'm puzzled about the fact that the CPU on my laptop spike at 100% for 10-15 seconds every few minutes even if the computer is iddle. Looks like the culprit is the service gathering information for the Reliability Monitor.

Here's a great article that describe what the heck Reliability Monitor is:

OK, I don't need it so how can I disable it?
- Right click on the Computer icon on your desktop and select Manage
- Expand Task Scheduler / Task Scheduler Library / Microsoft / Windows
- Right click on RAC / View / Show hidden tasks

The RACAgent should now appear. Right click on it and disabled it. That's it!
