Here’s a tip for those of you who own HP or Compaq laptops and netbooks. Most of these machines ship with HP Wireless Assistant, which basically does two things: display a popup telling you if your wireless network is on or off, and in some cases, enable a wi-fi on/off button on the keyboard.

But some versions of it moonlight by causing WMIPrVSE chew up 20% of available CPU power. People sometimes pay hundreds of dollars to get 20% more CPU power, so that’s not exactly welcome.
The problem is supposedly fixed in newer versions of HP Wireless Assistant. But frankly, you may be better served by just uninstalling the thing. It sounds like a free upgrade, especially for memory and CPU-limited netbooks.

It’s easy to remove this tool from Add/Remove Programs.
