Win7系统中的Power服务很重要，主要功能为管理电源策略和电源策略通知传递。不过一些用户发现Power没有启动，而我们去启动Power服务时却出现“错误2：系统找不到指定文件”的问题，当然遇到这个问题也不要担心，下面小编就带大家一起来解决。

Win7 Power服务无法启动“找不到指定文件”解决方法：

1、在任意位置新建一个文本文档（在任意空白处单击右键，选择“新建”—“文本文档”）；

2、打开“新建文本文档”，将下面内容复制进去：（红色部分）

3、在“新建文本文档”左上角依次点击“文件”—“另存为”，在保存界面首先将“保存类型”下拉菜单中选择“所有文件”，然后将文件名修改为“power on.reg”点击保存，然后双击导入注册表就OK了。

希望以上方法可以帮助大家打启Win7 Power服务。
