系统内存占用过高，一直达到百分之80到90，cpu占用却很少？？为什么？？我开的网页不多阿

这是我做的批处理,总共3项优化
你把下面那些命令保存到记事本里面，并把后缀名改为bat格式
运行完成后重启机器看看会不会改善一些吧

----------------启动项-------------
reg delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run /va /f
----------------清理垃圾文件------------------
@echo off
echo 正在清除系统垃圾文件，请稍等......

应该是中了病毒或什么插件，开机后自动运行占用了系统内存。建议在安全模式下杀毒，然后开始----运行----输入（msconfig）---保留输入法（ctfmon）和杀毒软件其余的全部取消。然后你在试试或许会解决问题，祝你好运。
