Speed up Windows XP - Reduce memory "wuauclt.exe"

My notebook's speed is too slow. HDD often is noisy "ga,ga,ga,ga...", when I will start anything. In this case, I can do nothing.

The cause is "wuauclt.exe". This program always watch Windows Update or Microsoft Update, like "What kind of updates did you do? Are there not enough updates?" Since these history will be increasing, will be big data volume before long. (My wuauclt.exe was 70MB)

A computer speed certainly become slow if its HDD keep to access. The way of speed up is initialization of wuauclt.exe. My computer was comfortable.
