打開“我的電腦”，進入以下目錄，這些目錄下的文件全部可刪：

C:\WINDOWS\system32\dllcache

C:\WINDOWS\Prefetch\

C:\WINDOWS\Temp\

C:\WINDOWS\下所有的補丁文件(隱藏文件)和日志文件(后綴為.log)：

再打開本地個人賬號目錄，路徑是C:\Documents and Settings\Administrator\Local Settings\Application Data，這些目錄下的垃圾文件也可全部刪除：如Cookies、Temp、Temporary Internet Files、Recent目錄:

徹底清理磁盤：點擊“開始”菜單中的“運行”，輸入“cleanmgr /sageset:99”命令，點擊“確定”后打開“磁盤清理設置”對話框，勾選全部的選項：：

再運行“cleanmgr /sagerun:99”命令執行清理操作:

點擊“確定”后開始執行清理工作，會依次彈出多個對話框：

請耐心等待清理工作執行完畢。

此方法煩鎖且效率不高，不建議使用，建議使用方法二。

點擊任務欄中的“開始”按鈕，選擇“所有程序”，再選擇“附件”，再選擇彈出菜單中的“記事本”，打開記事本程序：

設置磁盤清理選項：點擊“開始”菜單中的“運行”，輸入“cleanmgr /sageset:99”命令，點擊“確定”后打開“磁盤清理設置”對話框，參照方法一中圖片。

再執行保存的.bat程序，開始自動清理：

因為程序中一并清理了注冊表中的垃圾文件（Reg語句），所以執行此程序時建議關閉360，或者彈出360提示時選擇允許操作即可。

以后在需要時雙擊執行此程序即可。

打開360安全衛士，切換到“電腦清理”功能塊，選擇“一鍵清理”欄；

點擊“右邊”的“自動清理”按鈕，勾選下面的三個復選框，同時建議在下面清理頻率中選擇為“每周”：

切換到“清理垃圾”欄，先點擊右下角的“設置”按鈕，在彈出的“清理垃圾設置”窗口上單擊下面的“全選”，單擊“確定”：

退出“清理垃圾設置”窗口后單擊“開始掃描”按鈕即可。

再切換到“清理痕跡”欄，單擊“高級設置”按鈕，在彈出的“高級設置”窗口中選擇“全選”，單擊“確定”，退出“高級設置”窗口后單擊“開始掃描”按鈕開始掃描垃圾：

建議不要“全選”，只選擇你有安裝過的軟件即可。

掃描完成后執行“立即清理”工作。
