I found a way to reduce Vista CPU usage

[feuerri]

I just discovered that by changing the Start -> Control Panel -> Power Options in Vista Enterprise (running under build 3150), I was able to reduce the CPU consumption from 37-40% to about 17-20%.

By default, the Power Options setting was Balanced, but I changed it to Power Saver, and CPU usage went down quite a bit. You might also reduce it further by changing the search indexer behavior under the Advanced Settings when you Edit Plan Settings.

It probably should be there once it is confirmed to work for more than just me.

I can confirm that setting the energy settings to Powersaver and disabling any unneeded services brought my parallels cpu from 120% to around 15%

What services did you disable can you please post?

Yes, I can confirm that this works well. My control panel is set up slightly differently so to get to the option described by feuerri I had to go Start -> Control Panel -> System and Maintenance -> Power Options.
