1、打开"服务"窗口：services.msc（搜索一下，或者Win+x→运行都可以打开这个窗口）
2、找到”software prtection服务“，office出现错误提示的时候，这个服务是禁止状态。如果直接能够启动，那就可以把这个问题解决了。
3、小编的电脑通过服务窗口，不能直接启动software prtection服务，只能通过修改注册表的方式解决。打开注册表：
4、找到这个目录：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\sppsvc，这个看起来有点复杂了，不好下手啊。
还是直接双击一下注册表文件比较方便。把一下代码复制到一个文本文档里，把文件名改为“software prtection服务.reg”，双击这个.reg文件，即可修复software prtection服务的注册表。（或者通过百度网盘下载：http://pan.baidu.com/s/1sjQLwKX）
