下載 DLL 檔案，該如何安裝呢？

網頁沒提到如何安裝 DLL
所以我也不清楚該如何裝那個檔
我是用自動安裝的

我記得好像只要修改登錄檔就可以做到了說..

REGEDIT4

[HKEY_CLASSES_ROOT\Folder\shell\rootexplore]
@="由此開啟檔案總管"
[HKEY_CLASSES_ROOT\Folder\shell\rootexplore\command]
@="Explorer.exe /e,/root,/idlist,%I"
[HKEY_CLASSES_ROOT\Directory\shell\DosHere]
@="由此開啟DOS"
[HKEY_CLASSES_ROOT\Directory\shell\DosHere\command]
@="cmd.exe /k cd \"%1\""
[HKEY_CLASSES_ROOT\Drive\shell\DosHere]
@="由此開啟DOS"
[HKEY_CLASSES_ROOT\Drive\shell\DosHere\command]
@="cmd.exe /k cd \"%1\""

請問 BackgroundCMD 有什麼用途 ?

使用時機 會是在哪?

差別應該是在這裡？

The are many command prompt shell extensions out there. However,
as far as I can tell, none of them allow you to open a console window in
the current directory that you're browsing. Most will only allow you to
right-click a folder and have the command prompt start in that folder.

This can be quite a nuisance. When browsing a directory, I don't want
to have to go up one level just to start the command prompt. And what
about the desktop? Do I really have to browse to my user folder under
"C:\Documents and Settings\Administrator" just to get it working?

讓你"快速"在"任意目錄"內呼叫dos介面

尤其是中文目錄及很多層的目錄

翻成中文就是你不用回到上層目錄去按右鍵
你可直接在該目錄的任何地方按右鍵進入DOS介面

謝謝說明!!
這樣的功能 我也很需要的
小弟目前的解法 是做一個cmd 捷徑
只是沒有設定 "開始的位置"

這個不錯下，為使用者帶來相當直接和方便的CMD遊覽。 :)
而且這個BackgroundCMD也加入在桌面右鍵裏，時常都很需要這種功能。

要安裝DLL，將 BackgroundCMD.dll 放在system32資料夾。
然後在執行或CMD裏輸入 regsvr32 BackgroundCMD.dll 就可以了。
要反安裝的話，就輸入 regsvr32 /u BackgroundCMD.dll
