這幾天在做一個模塊，使用Java關(guān)閉重啟Windows Server 2008上的服務(wù)。開始使用的是j-interop。后來leader說，這玩意不行。ms已經(jīng)去掉了administrator的特權(quán)，要使用這玩意就需要用setacl.exe對注冊表修改，這exe包，打不開，看不到里面的東西，用起來心慌慌的。

　　后面么，發(fā)現(xiàn)當(dāng)你一超級管理員登陸時(shí)，windows上打開的cmd能直接運(yùn)行關(guān)閉啟動服務(wù)的命令。就來個曲線救國吧，好在不要求遠(yuǎn)程啟動服務(wù)，不然又是一番好忙。

　　廢話到此結(jié)束。

　　前提條件是，你隨意打開cmd，上面顯示的是“管理員”，如下圖所示，否則，還是有些功能不能實(shí)現(xiàn)。

　　 代碼如下：
