解决Windows 7、Windows Server 2008 R2安装2019年8月积累更新报错0x80092004

这是由于微软更改了2019年8月积累更新的数字签名验证方式，微软将SHA-1算法从更新包从删除，进而造成Windows 7、Windows Server 2008 R2无法验证更新包的完整性而报错。

解决此问题需安装以下2个补丁（注意选择适合自己操作系统的版本）：

1. SHA-2 code signing support update for Windows Server 2008 R2, Windows 7, and Windows Server 2008: August 13, 2019

2. Servicing stack update for Windows 7 SP1 and Windows Server 2008 R2 SP1: March 12, 2019
