今天有个水友向我反映，他的Win10专业版系统更新之后，出现错误代码0x80070424，然后小编就去查看他的系统服务，一般情况下Win10专业版系统更新/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Win10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，下面系统天地小编给出解决方案。

 

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。

 

直接双击该文件，弹出窗口后点击“是”即可。完成这些操作后，重启下系统就可以了。
