在电脑用久了容易变慢，其中除上“不小心”被安装了很多软件或插件外，另一重要的原因是我们用电脑遗留下来的垃圾文件，比如操作电脑产生的DLL或PF文件、打开OFFICE产生的临时文件、浏览网页产生的网页文件等。虽然这些操作完全可以用360等工具来清理，但如果我们能否自己写个程序来实现呢？答案是肯定，尤其是在公司加入域环境的很多人共用的电脑上，我们完全可以按需编写需要的功能。这里做一常用的bat程序，仅作抛砖引玉之用
操作方法
（01）首先，打开记事本。点击“开始”菜单，在“搜索程序和文件”文本框中输入“notepad”，并按回车，打开记事本：
（02）如果你是在XP系统下，或是你的Win7系统优化掉了“搜索程序和文件”功能，则需要点击“运行”命令，并按回车打开记事本：
（03）然后，将以下内容复制并粘贴到打开的记事本中：@ECHO offcolor 0aREM 优化更为彻底——可全自动删除域环境下所有本地帐户下的垃圾文件、自动删除系统更新遗留的补丁文件REM 针对家庭使用，增加了系统优化功能——自动判断是否需要优化，减少资源占用::echo 当前帐户：%username% ==本程序用于服务器时具有相当的危险性，请参照本程序源码REM操作！==ECHO

（04）再单击记事本中的“文件”菜单，在弹出的菜单中“另存为”命令：
（05）最关键的一步：在弹出的“另存为”对话框中，一定要选择“保存类型”为“所有文件”，然后在“文件名”中输入文件名并加上bat程序专用扩展名“”，如下图：
（06）至此，清理系统垃圾的bat程序已经制作完成，我们打开保存的目录，并右击这个“Bat清理系统垃圾”程序，从弹出的菜单中选择“以管理员身份运行”（如果是在Vista、win7 or more系统下）：
（07）注意，如果没有选择“以管理员身份运行”，则程序在执行过程中会显示“拒绝访问”，同时很多垃圾文件将不能清理干净，
（08）选择“以管理员身份运行”后，系统弹出“用户帐户控制”对话框，我们选择“是”既可：
（09）然后程序即会开始执行：
（10）因程序中使用了“reg”命令清理注册表垃圾，所以360安全卫士会弹出危险警告，务必要选择“允许程序的所有操作”，否则注册表垃圾不能被清理：
（11）待程序执行完毕后，会自动关闭这个窗口。
