這里給出一個(gè)清理電腦運(yùn)行過(guò)程中的垃圾以及部分使用痕跡的小程序、每天關(guān)機(jī)前運(yùn)行一下就可以保持電腦"干凈"、不會(huì)因?yàn)殚L(zhǎng)久使用造成系統(tǒng)變慢。
這個(gè)程序?qū)⑶謇砝?、并在清理完畢之后等?0秒后自動(dòng)關(guān)機(jī)，所以你不必等待清理完畢之后去手動(dòng)關(guān)機(jī)。

將以下給出的代碼另存為 清除系統(tǒng)垃圾.bat 的文件就可得到可以運(yùn)行的程序、注意后綴.bat。

其中有兩處需要你注意:
1.0
首先是最后一句代碼: shutdown -s -t 30 -f
這句代碼的意思是: 強(qiáng)制關(guān)閉所有打開(kāi)的程序、并等待30秒后關(guān)機(jī)、時(shí)間的參數(shù)就是30(單位是秒)、你可以自定義。
之所以等待30秒、是因?yàn)槟阌袝r(shí)可能不想關(guān)機(jī)，所以預(yù)留30秒的機(jī)會(huì)給你。取消關(guān)機(jī)的命令是: shutdowm -a、將shutdowm-a輸入"運(yùn)行"窗口、按下ENTER即可。
你可以在"運(yùn)行"窗口中輸入shutdown -s -t 30 -f、按下ENTER以觀看他的效果，然后將shutdowm-a輸入"運(yùn)行"窗口、按下ENTER觀看取消的效果。
快速打開(kāi)"運(yùn)行"窗口的快捷鍵是:"徽標(biāo)鍵+R"，在取消的時(shí)候輸入代碼將使你明白30秒的意義，當(dāng)然如果你不喜歡代碼、你可以將shutdown-a單獨(dú)保存為一個(gè).bat文件、專(zhuān)門(mén)用來(lái)取消關(guān)機(jī)。
如果你不需要、直接刪除這條代碼即可。

2.0
然后是第二句: start "" "%appdata%microsoftinternet explorerquicklaunch顯示桌面.scf"
意思是將所有窗口最小化、顯示桌面，這樣可以防止清理垃圾程序的窗口處于最前面、處在最前面可能由于某些原因使得清理過(guò)程暫停。
如果你不需要、直接刪除這條代碼即可。

完整代碼:

@echo off
start "" "%appdata%microsoftinternet explorerquicklaunch顯示桌面.scf"
