[求助]windowsXP 的一些进程有什么用？？

<P><img src="attachments/dvbbs/2005-1/20051250455365.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-1/20051250455365.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /></P>
<P>这个两个进程有什么用啊？我结束了，对系统好像也没有什么影响……
ALG.EXR、WDFMGR.EXE</P>

ALG.EXE是一个XP防火墙程序
