(Answer) (Category) distributed.net Faq-O-Matic : (Category) the Client software : (Answer) Disable multimedia keyboard buttons to increase Client speed
The speed of the distributed.net client running in Windows may be severely limited by the keyboard setting in Control Panel. New multimedia keyboards like those coming with Hewlett Packard computers have software which enables extra keyboard keys to launch web sites or control the speaker volume from the keyboard.

In my situation, I noticed the distributed.net client running very slow. I ran wintop.exe, a windows Powertoy, which is freely available from Microsoft and also downloadable as a standalone utility from add-ons page, to determine what programs were using the processor. Surprisingly, the client was only getting 2-3% of the processor time and the keyboard program was using 95-98% of the idle time of the computer. Once multimedia buttons were disabled in windows control panel, the client increased it's speed dramatically.

For HP computers, go to control panel, select Keyboard and then deselect "Enable multimedia buttons and onscreen display" so Windows will not use processor time to continually check multimedia keys for presses.
