爱华网平时使用电脑时，运行程序和打开文档都会在系统中留下垃圾文件，尤其是windows系统更新日积月累更会留下大量垃圾文件，且这些垃圾文件都不会自动删除，久而久之导致系统慢若蜗牛!下面就让小编给大家说说电脑慢怎样彻底清理电脑系统垃圾吧。
电脑慢彻底清理电脑系统垃圾的方法
方法一 手动删除
打开“我的电脑”，进入以下目录，这些目录下的文件全部可删：
C:WINDOWSsystem32dllcache
C:WINDOWSPrefetch
C:WINDOWSTemp
C:WINDOWS下所有的补丁文件(隐藏文件)和日志文件(后缀为.log)：
再打开本地个人帐号目录，路径是C:Documents and SettingsAdministratorLocal SettingsApplication Data，这些目录下的垃圾文件也可全部删除：如Cookies、Temp、Temporary Internet Files、Recent目录:
彻底清理磁盘：点击“开始”菜单中的“运行”，输入“cleanmgr /sageset:99”命令，点击“确定”后打开“磁盘清理设置”对话框，勾选全部的选项：：
再运行“cleanmgr /sagerun:99”命令执行清理操作:
点击“确定”后开始执行清理工作，会依次弹出多个对话框：
请耐心等待清理工作执行完毕。
此方法烦锁且效率不高，不建议使用，建议使用方法二。
方法二 编写批处理自动清理
点击任务栏中的“开始”按钮，选择“所有程序”，再选择“附件”，再选择弹出菜单中的“记事本”，打开记事本程序：
将以下内容复制到记事本，另存为后缀为.bat的批处理文件：
@ECHO off

exit
设置磁盘清理选项：点击“开始”菜单中的“运行”，输入“cleanmgr /sageset:99”命令，点击“确定”后打开“磁盘清理设置”对话框，参照方法一中图片。
再执行保存的.bat程序，开始自动清理：
因为程序中一并清理了注册表中的垃圾文件(Reg语句)，所以执行此程序时建议关闭360，或者弹出360提示时选择允许操作即可。
以后在需要时双击执行此程序即可。
方法三 利用360清理垃圾功能自动清理
打开360安全卫士，切换到“电脑清理”功能块，选择“一键清理”栏;
点击“右边”的“自动清理”按钮，勾选下面的三个复选框，同时建议在下面清理频率中选择为“每周”：
切换到“清理垃圾”栏，先点击右下角的“设置”按钮，在弹出的“清理垃圾设置”窗口上单击下面的“全选”，单击“确定”：
退出“清理垃圾设置”窗口后单击“开始扫描”按钮即可。
再切换到“清理痕迹”栏，单击“高级设置”按钮，在弹出的“高级设置”窗口中选择“全选”，单击“确定”，退出“高级设置”窗口后单击“开始扫描”按钮开始扫描垃圾：
建议不要“全选”，只选择你有安装过的软件即可。
扫描完成后执行“立即清理”工作。
