我刚刚在网上按照一个优化XP的系统服务的文章优化我的系统服务,优化完以后发现我的诺顿的自动更新病毒库的选项禁用了,点启用也没用.和哪些系统服务有关?还有就是我的任务管理器的进程那个页面下的"用户名"下面不显示用户名了.怀疑也与服务有关,是哪个啊??

1. the safe way of tuning system services is to create different `hardware profiles' and then for each profile signify which services to run. always keep a profile named, say, "default" and keep everything intact in that profile.

2. maybe u should set "task scheduler" to "automatic" in case the auto-update function of NAV/SAV depends on this
