我有一台使用了一年的华硕笔记本电脑，最初搭载的是 Windows 8.1。Windows 10 发布后，我毫不费力地升级到了 Windows 10。
尝试更新到 11 月更新 (Threshold-2) 或更新的 Redstone 就是不起作用。升级开始，最后 Windows 重新启动。然后在升级过程进行到大约 40% 后，升级被中止，Windows 恢复到以前的版本。

我尝试了 Windows 更新、媒体创建工具或 Win 10 升级助手，但都没有任何效果。
卸载 Norton AV 并使用 Windows Defender。
到目前为止，我还没有尝试过干净的全新安装，如果可能的话，我想避免这种情况。
有什么提示或建议吗？
