今天网上有个同学找到我说，他的win8.1系统不管用什么方式激活，都出现错误代码0x80070424，后来笔者建议让他使用最新版的kms神龙版试试，结果试后还是一样，然后笔者就去查看他的系统服务，一般情况下系统激活依赖于服务software protection，但是我在他的系统服务里却找不到这项，这很明显是系统服务丢失引起的问题，只不过在win8.1系统上提示为错误代码0x80070424，如果是win8系统，就会明确的提示“指定的服务部存在”。那么找到了问题所在，接下来就是修复系统服务software protection了，下面亦是美网络给出解决方案。
tips：没有software protection服务，不仅仅系统激活时会遇到错误代码0x80070424，而且系统更新补丁时也会出现这个问题。
如何查看系统服务software protection是否存在？
按下win+R组合键，打开运行，输入 services.msc，回车后即可打开服务，然后查看是否存在“software protection”。
如果software protection服务不存在，如何修复？

复制好后，在桌面上新建一个记事本spp.txt，然后将复制的内容粘贴进去，保存后将文件后缀改成reg，也就是把spp.txt修改成spp.reg。
如果你担心自己操作不好，也可以下载笔者准备好的文件：http://pan.baidu.com/s/1mgMINEC
直接双击该文件，弹出窗口后点击“是”即可。
完成这些操作后，重启下系统，再重新进行win8/8.1系统的激活就可以了。
激活win7/8/8.1+office2010/2013等请参考：
