windows之家1.如何修复微软Windows7激活失效ID错误?
按照官方的说明和方法，将Windows 7激活并不困难。
但有的用户在激活Windows 7过后的一段时间里，系统忽然会告知激活状态无效，或显示激活错误，同时还会出现产品ID无效的提示。 文章开始部分所描述的情况，并非只存在于中国的用户中，国外用户也有此类情况发生。
笔者现将国外用户遇到的类似情况，以及解决方法拿过来和大家分享。 用户在激活Windows 7系统后，如果系统属性中忽然显示激活状态是“未激活”，此时可以在“命令提示符”先使用“slgmr -dli”或“slmgr -dlv”命令查看具体的激活信息。
此时，系统将产生“错误： 0*80070422”的提示。 通过运行“slui。
exe 0*2a0*80070422”命令可获得提示“错误 0*80070422：该服务不能启动，可能是因为它被禁用或者是因为它没有相关的启用的设备” 由此，我们就找到了错误的根本原因所在。 这其实并非是安装盘或安装程序损坏，也并非是因为盗版Windows 7或盗版软件导致系统激活失效，而是因为系统服务的“软件保护服务（sppsvc。
exe）”出现了问题——被禁用了。 小知识：什么是软件保护服务？ 在Windows 7中，软件保护服务是用于检测安装和Windows和Windows应用程序的数字许可证的。
比如，该服务可以阻止试图破解Windows 7，或拒绝一些未经签名的应用程序。 知道了问题所在，解决问题就简单了。
在系统服务中，将sppsvc。exe服务再次开启就可 在sppsvc服务中，将其启动类型设置为“自动（延迟开始）”，重启后即可解决激活问题。
编辑点评： 在Windows 7的系统服务中，sppsvc服务可以算是相对比较特殊的一个。它的主要功能是防止Windows 7被非法破解或激活，或是用户给系统安装一些“未经签名”的软件，比如一些第三方的破解软件等。
如果用户遇到此类问题，可以参照上面的方法予以解决。
2.重新安装Windows10系统后不激活怎么办呢?
