运行services.msc ，服务项里面没有Cryptographic Services ；如果有吵稿的话，就直接启动。如果没有的话，就看看下面的方法。跟Cryptographic Services有关的系统功能无法使用。关键可能就在此。选择方法：新建文本文档，输入内容:Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCryptSvc]"DependOnService"=hex(7):52,00,70,00,63,00,53,00,73,00,00,00,00,00"Description"="提供三种管理服务: 编录数据库服务，它确定 Windows 文件的签字; 受保护的根服务，它从此计算机添升凯孝加和删除受信根证书机构的证书;和密钥(Key)服务，它帮助注册此计算机获取证书。如果此服务被终止，这些管理服务将无法正常运行。如果此服务被禁用，任何依赖它的服务将无法启动。""DisplayName"="Cryptographic Services""ErrorControl"=dword:00000001"ImagePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,00,76,00,63,00,68,00,6f,00,73,00,74,00,2e,00,65,00,78,00,65,00,20,00,2d,00,6b,00,20,00,6e,00,65,00,74,00,73,00,76,00,63,00,73,00,00,00"ObjectName"="LocalSystem""Start"=dword:00000002"Type"=dword:00000020[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCryptSvcParameters]"ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,72,00,79,00,70,00,74,00,73,00,76,00,63,00,2e,00,64,00,6c,00,6c,00,00,00"ServiceMain"="CryptServiceMain"[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCryptSvcSecurity]"Security"=hex:00,00,0e,00,01[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCryptSvc孙岁Enum]"0"="RootLEGACY_CRYPTSVC0000""Count"=dword:00000001把文本文档另存为CryptSvc .reg文件，双击此文件 注册到注册表中。关机重启。然后运行services.msc ，找到了Cryptographic Services，此时安装补丁，成功。
