有部分win7系統用戶在使用過程中遇到這樣一個情況，就是在啟動power服務的時候發現無法啟動，并提示“錯誤2：系統找不到指定文件”，如果這個服務沒有開啟計算機就無法正常使用，要怎么辦呢？接下來給大家講解一下具體的解決方法如下。

推薦：win7 32位系統下載

步驟：
1、在win7系統中任意位置新建一個文本文檔（在任意空白處單擊右鍵，選擇“新建”—“文本文檔”）；
2、打開“新建文本文檔”，將下面內容復制進去：

3、在“新建文本文檔”左上角依次點擊“文件”—“另存為”，在保存界面首先將“保存類型”下拉菜單中選擇“所有文件”，然后將文件名修改為“power on.reg”點擊保存；

4、在剛創建的“Power on.reg”文件上單擊右鍵，選擇“管理員取得所有權”；

5、然后雙擊運行該文件，在彈出的提示框中選擇“是”，即可重新開啟此服務。
