几天前，微软发布了新更新 KB5016616。当尝试安装 Windows 更新时，重新启动 PC 后，Windows 提示“我们无法应用更新，正在回滚”。我尝试了所有能找到的办法，但都没有结果。
我从控制面板重新安装了 Dotnet Framework 3.5，扩展了系统保留分区，手动下载了更新并尝试安装，但都以 0x800f0922 结束。尝试通过 Microsoft 的“升级此 PC”选项进行更新，显示“感谢您使用最新版本的 Windows”。有什么建议吗？日志的一部分如下：

我目前所做的：
- 重置 Windows 更新
- 重命名 SoftwareDistribution 文件夹
- 手动下载更新并从 windows10.0-kb5016616-x64_94a65010a34b5bae2324c9433d1cae0b9d906d8c.msu 安装
- 将 SystemReserved 分区大小调整为 600mb
- 尝试通过 Windows Udate Minitool 安装
- 解决 Windows 更新问题
- 将应用就绪服务设置为自动（延迟）

我如何解决这个问题：
我还检查了 cbs.log (C:\Windows\Logs) 并搜索了“错误”短语。我发现了以下行：
000005db BFSVC: 'Failed to get system partition! Last Error = 0x3bc3'
我谷歌了一下，发现磁盘从 MBR 转换为 GPT 时也遇到了类似的问题。一周前，我也将磁盘从 MBR 转换为 GPT，并使用 diskpart 检查了分区列表。磁盘的分区列表如下：
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 600 MB 1024 KB
Partition 2 Primary 929 GB 601 MB
Partition 3 Primary 1300 MB 930 GB
我这里没有系统分区，但 Windows 正在寻找分区类型来保存文件。
我使用以下命令转换了分区 3：
select partition 3
SET ID=c12a7328-f81f-11d2-ba4b-00a0c93ec93b
现在分区列表如下：
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 600 MB 1024 KB
Partition 2 Primary 929 GB 601 MB
Partition 3 System 1300 MB 930 GB
重新启动后我就能完成更新。
