在電腦用久了容易變慢，其中除上“不小心”被安裝了很多軟件或插件外，另一重要的原因是我們用電腦遺留下來的垃圾文件，比如操作電腦產生的DLL或PF文件、打開OFFICE產生的臨時文件、瀏覽網頁產生的網頁文件等。雖然這些操作完全可以用360等工具來清理，但如果我們能否自己寫個程序來實現呢？答案是肯定，尤其是在公司加入域環境的很多人共用的電腦上，我們完全可以按需編寫需要的功能。這裏做一常用的bat程序，僅作拋磚引玉之用。且看xp清理係統垃圾bat教程。
xp用bat清理係統垃圾的方法:
1、首先，打開記事本。點擊“開始”菜單，在“搜索程序和文件”文本框中輸入“notepad”，並按回車，打開記事本：
2、如果你是在XP係統下，或是你的Win7係統優化掉了“搜索程序和文件”功能，則需要點擊“運行”命令，並按回車打開記事本：
3、然後，將以下內容複製並粘貼到打開的記事本中：
@ECHO off
color 0a
REM 優化更為徹底——可全自動刪除域環境下所有本地帳戶下的垃圾文件、自動刪除係統更新遺留的補
丁文件
REM 針對家庭使用，增加了係統優化功能——自動判斷是否需要優化，減少資源占用

4、再單擊記事本中的“文件”菜單，在彈出的菜單中“另存為”命令：
5、最關鍵的一步：在彈出的“另存為”對話框中，一定要選擇“保存類型”為“所有文件”，然後在“文件名”中輸入文件名並加上bat程序專用擴展名“.bat”，如下圖：
6、至此，清理係統垃圾的bat程序已經製作完成，我們打開保存的目錄，並右擊這個“Bat清理係統垃圾.bat”程序，從彈出的菜單中選擇“以管理員身份運行”（如果是在Vista、win7 or more係統下）：
7、注意，如果沒有選擇“以管理員身份運行”，則程序在執行過程中會顯示“拒絕訪問”，同時很多垃圾文件將不能清理幹淨，
8、選擇“以管理員身份運行”後，係統彈出“用戶帳戶控製”對話框，我們選擇“是”既可：
9、然後程序即會開始執行：
10、因程序中使用了“reg”命令清理注冊表垃圾，所以360安全衛士會彈出危險警告，務必要選擇“允許程序的所有操作”，否則注冊表垃圾不能被清理：
11、待程序執行完畢後，會自動關閉這個窗口。
不知道【xp清理係統垃圾bat】的話，按照以上的內容來設置即可。還有其他的類似問題或者電腦係統下載後安裝使用的疑問都歡迎上係統粉查看解決的方法。
