1.WIN10专业版更新补丁出现0x80070424错误咋办?

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？复制下列内容（分割横线不要复制进去）内容：Windows Registry Editor Version 5。 00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sppsvc]StartProtected=dword:00000001DisplayName=@%SystemRoot%\\system32\\sppsvc。

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。
