It works for me, 

a.exe		99%
idle		01%

Do you run NT-Server or NT-Professional?
Anyway, there is a key in the registry which tunes up the PC for
background processes, it is called 'LargeSystemCache'
Start 'regedit' lookup these keys in registry and set them to '0'
unless they are already '0'. (They are defined twice or more in different
Control Sets).
