原因分析:
可能是software protection服务丢失,即在services中无法找到该服务。
解决方法:
1、按”win+R”组合键,调出运行框,输入: services.msc 并回车,查找software protection服务:
2、如果找不到software protection服务,那么我们可以参考如下方案,通过导入software protection键值,重建software protection服务,来解决该问题:
3、新建一个记事本文件,将以下文字复制粘贴到记事本中,以“sp.reg”命名并保存于桌面。

4、请您双击“sp.reg”,当系统提示您是否确认导入注册表时,请点击“是”。之后会有提示说明已经成功导入注册表。
5、重启后,再次进入”服务”控制面板查看,可以找到software protection服务,右击并选择启用。
software protection是一个重要的服务,winxp系统提示无效的产品密钥,且报错0x80070424都是由此服务丢失导致的,遇到这种故障的用户可以通过小编介绍的方法,导入修改注册表便可恢复这项服务。
