Vista/7 的環境變數設定，有些和 2000/XP 的不同。找了參考資料，想把適合的設定給 2000/XP 使用。起初是用手動設定，驗證後感到滿意，便將設定寫成批次檔，方便日後修改。

此範例腳本，加入了 %LOCALAPPDATA% 變數，以及對 .msc 檔案的支援。

請問使用時機為何?
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATHEXT /t REG_SZ /d ".COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC" /f > nul
把 ".MSC" 挪到 ".EXE" 之前不就夠了嗎?
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATHEXT /t REG_SZ /d ".COM;.MSC;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH" /f > nul

起初的設定是將 .msc 放在最前面，測試後不符合希望的結果。

再提供一個檔案。這是為 Windows 2000 伺服器家族寫的，不過 XP/2003 同樣能使用。
